titanium bar Nitinol material can become earthquake

A length of about 10 seconds of test input on a flexible nitinol conducted , we found that protection may help bridge earthquake safety.
In this test , the new alloy buy titanium bar greatly reduces the extent of the damage a length of about 100 feet ( 30 meters ) of concrete bridge model. Scenario simulation is 1994 Los Angeles Northridge (Northridge) earthquake . . That quake killed 57 people and caused extensive damage in Los Angeles .\University of Nevada research team simulated a magnitude-8.0 quake and shake the bridge for 10 seconds. titanium wire price This time is sufficient in the Northridge earthquake razed bridges and flyovers .
Since the bridge has reinforced nitinol , so after a violent shaking , it still did not fall. Although the partial destruction of the concrete , but the overall infrastructure remains intact . .
Engineering professor M. Saiid Saiidi said nitinol flexible.
He told Reuters in a telephone interview , said : "This is a typical shape memory material ."
"They remember what they were before the earthquake looks like , they are often able to keep the prototype. They experienced the earthquake deformation , but soon they went back to the titanium plate suppliers previous appearance ."

titanium axle Research Investment casting with

Research Investment casting with titanium oxide ceramic shell -shell technology for
Titanium Investment casting technology to meet the needs of the aerospace industry and developed , has been widely used in aerospace titanium titanium components and civilian material titanium structures manufacturing. Practice has proved that the titanium alloy precision casting technology has become almost no margin of several forming processes to obtain maximum effectiveness of a process [ 1-3] . With the extensive application of titanium castings , its increasingly stringent quality and usability requirements , in addition, the level of costs also limit its application prospects is an important indicator . Graphite was low cost but poor quality of the casting surface , and is not suitable for the production of thin-walled complex parts [ 4 ] , but with the surface layer of refractory metal or yttrium oxide surface layer ceramic shell can be cast out of high quality titanium castings, but the cost is very high [ 5,6 ] . For this study the low -cost , suitable for the production of complex thin-walled shell technology for a new type of titanium oxide ceramic Investment casting is .
1 Materials and experimental methods
1.1 The main system shell material

The surface layer and the adjacent surface layer of slurry : The main components of zirconia refractories , size of 30μm or less. Organic zirconium sol as a binder , the size of the refractory rubber match should be 10 ~ 15nm.
The surface layer and the adjacent surface layer of sanding : the main component of the surface layer is made of zirconium dioxide sand , the size of 150 ~ 300μm. To reduce costs, the use of adjacent surface layer is mainly composed of ZrO2.SiO2 zircon sand . The results show that the diffusion of Si is not seen in the casting , it is feasible the use of zircon sand .
Back layer system shell material: silica sol as a binder , using Morley powder and sand as refractories.
1.2 system shell method
The order of addition batter titanium plate suppliers followed binders , refractory powder , trace additives. Minor amounts of additives to improve the stability of the coating role is to improve the wettability of the material and the mold , etc., and to prevent drying of the surface layer after the return water soluble additive is selected micro- organic material can be removed during the calcination . Stir batter than 2h at room temperature ( about 20 ℃) ​​in the air , after the return of 1h to use .

O face the same batter pulp and raw materials , the production process is the same, only slightly smaller concentrations . Slurry feed back order binders , refractory powder. Also need to continuously stirred slurry back more than 2h , after the return of before use. Depending on the size of the backing layer casting , painted hanging normally takes 4-9 layers.

Drying : Drying time the surface layer and the adjacent surface layer are 24h, the temperature is 20 ℃, relative humidity of not less than 60% , the drying time of the backing layer is not less than 4h, the same as other conditions and the surface layer .

Roasting process : After dewaxing gas shell fired at without protection roaster .

Optimization of two main titanium rod for sale parameters of the Shell Technology

In all system shell process parameters on shell quality and ultimately a greater impact on the quality of castings are: batter ingredients, namely powder -liquid ratio , dewaxing and roasting process parameters [ 7 ] , this research labs now there are devices on the above parameters in-depth study and optimize selection.


titanium axle powder -liquid ratio across the layer

2.1 powder -liquid ratio across the layer of coating thickness and suspension rate impact
Table 2 powder-liquid ratio on the opposite layer coating thickness and coating suspension rates . The results show that the greater the surface pulp powder -liquid ratio , the greater the thickness of the surface coating , the coating suspension , the better. Generally believed that if the surface coating is too thin (<0.2mm), the shell will be affected by sanding the surface , the roughness increased. If the coating is material titanium too thick (> 0.6mm), the coating , poor mobility, easy accumulation , during the drying or firing cracks easily [ 7 ] , which in this study has also been confirmed in the present study therefore the powder in the liquid ratio should be controlled between 5.0:1 - 6.0:1 .
Table 2 in the powder -liquid ratio of coating performance
Table2 Effects of solid / liquid ratios on the properties of coating
4.0:1 5.0:1 5.5:1 powder -liquid ratio 6.0:1
Coating thickness / mm 0.11 0.25 0.36 0.65
Coating suspension rate / % 88.3 90.1 93.1 97.6
2.2 Effect of shell powder -liquid ratio and calcination temperature on the room temperature and high residual strength
Figure 1 shows the ratio of powder and liquid at room temperature and high temperature effect on residual strength . Strength of the sample is composed of five levels of plasma and surface sand composition , each drying 24h, continuous coating hanging , firing 4h. Flexural strength of the strength test .

Figure 1 powder-liquid ratio of the residual strength of the opposite layer
Fig.1 Effects of S / L ratios on the remain flexural of
surface coats baked at different temperatures
The results showed that the powder -liquid ratio improved shell specimen bending strength . Calcination temperature is increased , the flexural strength increases with . Since 1100 ℃ ZrO2 occurs near the phase transition , so that the strength in the vicinity of this temperature increase is not significant , but the phase change process , the lattice of unstable energy increased activity increased , so should be avoided in the actual production of the calcined temperature. After calcination at 1200 ℃ by titanium wire price the high ratio of powder and liquid coatings ( 6.5:1 ) intensity decreased slightly reason: Because the coating is too thick , a slight increase in the calcination process of internal defects , thereby affecting its strength. From the results in Table 2 and Figure 1 show that the optimum value of 5.5:1 powder-liquid ratio of the surface layer material . The firing temperature is preferably at about 1200 ℃, but for small pieces of calcination temperature can be set at around 1000 ~ 1050 ℃.
2.3 Optimization of process parameters dewaxing
For this study cast casting spade 150mm × 100mm , thickness of 2.5mm, the microwave dewaxing process, the time relationship between the intensity of the microwave shown in Figure 2 and dewaxing .
Figure 2 microwave intensity and dewaxing time
(a) the inner surface intact ; (b) inner surface microcracks
Fig.2 Effects of different titanium rod for sale microwave intensities on dewaxing time
(a) no crack; (b) have cracks
Figure in a district that is less than 70% when the microwave intensity , dewaxed shell inner surface smooth , with little residual wax, no visible cracks. When the microwave intensity is too large (b zone ) , dewaxed shell intact , although overall , but there are a few cracks in the surface layer , with the microwave intensity increased the number of cracks increases , the reasons for this phenomenon may be due to over- heating rate fast , since the internal stress of the inner and outer layers of different thermal expansion coefficients of the time to produce slack . Therefore microwave intensity used in this study was 50% , dewaxing time about 8min. Through other experiments show that this dewaxing process useful in the present titanium rod stock study not only the spade member is equally applicable to other shapes and sizes of parts.

titanium standard parts Titanium crazy man in the world

Stone is always engaged in the processing of private enterprise , general manager of titanium Baoji City, Shaanxi Province , in June this year, he came to discuss business matters Zunyi Titanium plant at night in Caigen restaurant for dinner , I accidentally knew he has a titanium sheets for sale deep and titanium Love .

Forty-six year -old stone overall , looks very lean and capable spirit . He has experienced four car accident, serious bodily injury , arms , feet , thighs, Jingbo multiple fractures have occurred . He said he had been able to walk around today , and can drive to the country to discuss business, thanks to its titanium support from the new life , let him walk freely and enjoy the fun of a new life . Know I was collecting material for their writing , "said titanium Big Pan " to introduce the knowledge of titanium , stone aggregate is also quite proud to tell me , I saw his outstretched right arm to roll up their sleeves that you see here on my arm titanium bone . Its the same to Baoji, Shaanxi Baoji Titanium Technology Co., Ltd. Gao Lin , general manager adds, titanium body very stony total , there are titanium plates , titanium screws, titanium bone , etc., also said that the stone is always the biggest beneficiaries of titanium person .
After listening to rock aggregate bond forged titanium , titanium makes me feel incredible. Although titanium is the biological parent metal , I still suspect and must be " titanium" and more on the body no good ! Unexpectedly Stone always said , all right, I'm no different with the previous freedom of movement . The total line when farewell stone back to Xi'an , according to the etiquette we shake hands with another , did not think his hand is so there is grip , which I regarded as " titanium" convinced , also felt the titanium to the crazy world of men brought endless madness titanium wire price charm.
If experience makes stone and titanium total surprise , then, that 29 -year-old British teacher Gavin Rees and titanium that is really thrilling experience , shattering titanium madness.
According to the British "Sunday Mail" reported , Gavin Rees in a near-fatal skiing accident sustained severe head , facial bones and skull fractures and unrecognizable because even friends can not even recognize . Fortunately, the doctor for his purposes facial bone reconstruction surgery - with up to 21 " Titanium Skull" substitute its skull defect , and then to 131 screws tight to be fixed in order to eventually get rid of the death of his miraculously . Allegedly, 70% of head and now Gavin is composed of titanium , the metal content of his head than any other person in the world !
Talking about that crazy skiing accident , Gavin Rees recalled: "I facial bones are squeezed back , the whole head is deformed and friends have all been frightened , saying that they have been completely unable to recognize me . My injury is a mess , blood all over the place . friends will I wrapped in blankets , while singing to keep me awake while waiting for rescue personnel arrived . "
Happy is 19 hours of surgery to put " titanium head ," Gavin Rees has replaced the guy 's nose shape , people also become beautiful .
It is reported that doctors decided to rebuild destroyed Gavin Rees facial bone structure with titanium . As the face completely deformed , according to the doctor had Gavin passport photos as a guide to rebuild his facial structure . Interestingly, when informed that his facial bones should be replaced when titanium - Gavin require doctors to carry small change his appearance , put his nose made ​​of titanium alloy handsome George Clooney looks like.
Doctors said that because of the metal content of Gavin Rees head than any man in the world , from students to their nickname "Golden headman " - sometimes friends curiously tapping his head , titanium sheets for sale they also really will be issued clanking metal sound of it !
The above two cases associated with the titanium living textbook tells us that titanium is indeed a good thing, called the body regenerate bone. Men in this world juggling , crazy, looking for adventure stimulation, can not be avoided in the awesome scenery infinite probability , relatively woman, a man in distress is much larger than the crazy woman . We do not advocate the men go crazy adventure, but we want to bless a man of adventure , ready for their first 207 good human bones , " titanium" , which is " titanium titanium are " on the man's care.
In the green grass, when you see men holding up play to do with titanium golf club to hit a ball , you will find a combination of titanium and man is so perfect , the mighty , the moment when the ball hit fly , you will feeling of titanium and titanium titanium wire manufacturers crazy man in the world opened the prelude - to show the beauty of masculine men titanium combined .

titanium standard parts Titanium " has good biocompatibility

Titanium wonderful woman in the world
Amy is a woman 's nature, even though she has " beauties Biyuexiuhua " of beauty, she would not give up the pursuit of beauty , women, the icing on the cake for a lifetime pursuit. Since ancient times, gold and silver diamond jade, pearl Ma Naobei are all dressed female beauty jewelry, it is also a woman in the beauty of nature to explore the beauty of decorative objects found on the end of the century a noble metal pro-biotic " titanium" relying on human skin affinity, began to become ornaments , into a brilliant woman in the world , adorned with endless wonderful woman in the world unique .
Because titanium jewelry beauty products, became the icing on the cake icing titanium , thus more beautiful woman in the world , hence the more wonderful , titanium let a woman when the wife "Titanium " beauty .
The first time I saw a woman titanium ornaments , now or in the China Nonferrous Metals Industry Association, titanium , zirconium and hafnium club president and general manager of Baoji Titanium Group Wang Hanchen there to see. Wang always to remember that when the nation's largest titanium sponge production plant in Zunyi Titanium plant visits , took out a silver bracelet , said that this is done titanium bracelet, very lightweight , lightweight feel worn on the hand good . Later, by a friend in Taiwan where I saw a more refined workmanship titanium necklace , titanium rings, titanium earrings, titanium earrings and so on. At this time, I was aware of titanium in the twenty -first century will have a deep bond with the woman 's story will happen , perhaps because women in the world appear to produce a titanium jewelry titanium wonderful beautiful change.
Query data , I found that titanium is indeed magical, it can not only decorative features of the modern woman's beauty , dotted Li Jingbo , the whitewash the hand of the show, but also let some gloomy female breast rise, swagger - this is the new nickel-titanium bra alloy charm.
Breasts is regarded as the most notable female secondary sex characteristics . It is said that the habit of Oriental women bra Bra from Yang invention. Social progress , changing times , always had the habit of bra Oriental women have begun to wear sun dress , low-cut dress and other clothing , and some also use a variety of beautiful bra to beautify the shape of the breast .
In addition to the size of the female breast affected by hormones , but also by a variety of genetic factors , environmental factors, nutrition , weight , physical exercise. Some people in order to make up the breasts while taking hormone drugs , endocrine disorders will inevitably bring , the beauty of women must be careful to use. Breast is it has the potential to cause harm to breast tissue under the negative influence . It is understood that the U.S. Food and Drug Administration (FDA) prohibited such products to market. Some foreign countries have silicon breast augmentation capsules bags in vivo safety questioned .
Experts recommend physical exercise plus choose the ideal bra is the most appropriate. Bra has recently introduced a new foreign high-tech , with its bottom rim "shape memory alloy" in place of nickel-titanium alloy when heated to a certain temperature , i.e., a predetermined shape to reply , and it is more flexible than the existing rims even after washing distorted , just wore that tie with the temperature curve , the elastic than normal rims doubled in size, will not be deformed . With the popularization and application of titanium , I believe that soon the natural beauty of oriental women will benefit from them.
Jewelry made ​​of titanium , titanium system bra will make wonderful woman in the world . Advantage of titanium is " titanium " Light : titanium, stainless steel accounts for about half of cobalt, chromium and other alloys , it is much lighter than gold 16.3 , in making earrings, necklaces and other jewelry when obvious advantages ;
"Titanium " has good corrosion resistance : it embodies the advantages of jewelry is non-corrosive , not color, can long maintain a good luster, and is not afraid of water
"Titanium " has good biocompatibility : good corrosion resistance characteristics of titanium and people make it after long-term exposure does not affect its nature , does not cause allergies. titanium sheets for sale Now in the medical field has been widely used. Therefore, people who are allergic to metal can boldly wear titanium jewelry ;
"Titanium " Can coloring : titanium metal has a very interesting feature , titanium placed on certain current through the electrolyte , the surface will be based on the electrolytic oxide film , and the thickness of the oxide film may decide to change the color while and no external element. Now do the colors are gold , black, blue , brown , flowers and other colors . This feature makes it more colorful jewelry design , titanium wire price more fashionable ;
High titanium hardness, not easy to deformation , unlike ordinary wear gold and silver jewelry and other period of time need to re- shaping.
Since the material properties of titanium and unique cultural connotation , she will become after the precious metals platinum, gold jewelry is another stylish and classic metal ! Recent years, the Western countries and Japan, South Korea , titanium jewelry industry is booming , and ascendant, titanium jewelry has become a fashion, classic , conservation , personality, health synonymous ! believe that in the near future , Xiuwaihuizhong , sunny temperament of women will add in the next Jin let panacea "Titanium " titanium sheets for sale charm !

titanium standard parts Thermal conductivity of titanium small

Thermal conductivity of titanium small , non-magnetic , superconducting properties also have some titanium , memory performance, and hydrogen storage properties and other functions.

Since titanium has a series of titanium sheets for sale excellent performance, very rich in resources , after the advent of the industrial production of titanium , immediate attention by the world in general . 1947 United States take the lead in the industrialized production of titanium sponge , then produce two tons of titanium sponge , 1957 on the development of more than 15,000 tons . Japan in 1952, the former Soviet Union have begun in 1954 with an average annual production of titanium sponge . China also began trial production of titanium sponge in 1958, and now has formed a complete industrial system of titanium . Currently, there are countries in the world titanium industry mainly the United States , CIS, Japan, Britain, China and Germany.

The first is the application of titanium in military and aviation industry from the beginning . As early as 1951 the United States will be on the plane for titanium , used in aircraft to the United States in 1961 amounted to 3,940 tons of titanium manufacturing , accounting for 77% of the total amount of titanium , if the missile and space technology combined with titanium , titanium accounting 95% of the amount of material . The former Soviet Union , the United Kingdom titanium are mainly used in military and aerospace industries. In the 1970s , the excellent performance of titanium gradually generally recognized in civilian industry , titanium used in the metallurgical, chemical, electric power and other civilian industries increased titanium wire price year by year , the amount has been growing steadily . Now, the U.S. non- aerospace titanium has more than 30% , 50% CIS , Japan, due to historical reasons, almost all titanium for civilian industry.

China is a country very rich in titanium resources , after decades of development , has been formed from titanium, titanium sponge , titanium and titanium smelting production , titanium equipment manufacturing as a whole industrial system. China titanium for the aerospace industry is also the rise of our country in the 1980s determined to promote the principle of civilian titanium , the state has taken a timely manner to support the policy , titanium industry was on the path of stable development. However, the current scale of production in China and titanium and titanium industry there is a great gap between the world's developed countries , in the civil industry is also a titanium sheet suppliers small amount of titanium , the reason is the superiority of titanium material has not been widely recognized , coupled with the high price of titanium material many companies can not afford to make a direct impact on the promotion of the use of titanium materials. For China 's titanium industry has been rapid development , we must vigorously publicize and promote the use of titanium metal, titanium metal material so that the superiority and the use of titanium material can bring economic and social titanium sheets for sale benefits are well known.
