Titanium and titanium plates solid solution and aging treatment

When the solution plus a comprehensive aging heat treatment process . Solution treatment for aging effects and processes have a tremendous impact. Therefore , in determining the process must be integrated together to consider in order to get a satisfactory overall performance.
In nearly a titanium and β stabilizing element content smaller a + β titanium alloys ,medical titanium bars strengthening effect due to the tempering of martensite caused limited , requiring the organization after solution treatment on the overall performance should be better . Aging can only play a supporting role in strengthening . Such titanium process selection can refer to affect the heating temperature and cooling rate on microstructure and properties of TC4 titanium alloy .
At higher levels of β stabilizing element a + β titanium alloys , metastable β phase in aging decomposition can cause hardening, while the plastic drop. Accordingly , the organization requires plasticity after solution treatment is better .
Β titanium alloy can be heat treated to high temperature solution treatment and not only causes unnecessary oxidation of coarse grains , and make the decomposition time is a dispersed phase , the grain boundary area is narrowed light , resulting in a sharp decrease in ductility after aging . Solution treatment is too low to make the grain boundary bright areas widened even be uneven precipitation , resulting in no enhancement of the organization .
Solution treatment and aging plus titanium and titanium alloy solid solution treatment process . Listed within the process , still be based on the actual chemical composition ,titanium stockists a + β / β transformation point , the original organization before heat treatment equipment used and the like , the final heat treatment process to determine by experiment .
Titanium and titanium alloy produced in the solution process for the replacement of elements of martensite is supersaturated , does not cause as large as martensitic steel lattice distortion , titanium martensite is not so hard . Furthermore, the metastable β -phase is relatively low strength , and low temperature cold pre-aging before aging have greatly accelerated the rate of decomposition of the metastable β -phase .
