In order to obtain a high concentration of $\alpha$ precipitates the aging temperature are vital as they usually determine the volume fraction of $\alpha$ platelets that form with also influence a high yield strength. There are 2 ways in which $\alpha$ particles are annealed. (1) Annealing at high temperatures (2) two stage annealing.   It is often difficult to get substantial distribution of alpha particles in titanium alloys that contain a high concentration of $\beta$ stabilizers, in theses cases studies suggest presaging of the sample allows a more uniform distribution of $\alpha$ particles. Another study suggests that more homogeneous distribution is achieved at dislocations by cold working prior to aging. The persistent problem is that the a phase generally appears preferentially at grain boundaries, on intra-granular defects and along dislocation lines, making it rather difficult to obtain a uniform and dispersed a phase distribution.  References  @article{ivasishin_comparative_2008,  title = {A comparative study of the mechanical properties of high-strength β-titanium alloys},  volume = {457},  issn = {0925-8388},  url = {http://www.sciencedirect.com/science/article/pii/S0925838807006998},  doi = {10.1016/j.jallcom.2007.03.070},  abstract = {The mechanical properties of four commercial β-titanium alloys (TIMETAL-LCB, Ti-15-3, β-21S, and VT22) were compared in the solution-treated-and-aged (STA) condition following thermomechanical processing comprising β solid solutioning, cold deformation (CD), continuous rapid heating, and final aging. The peak temperature during the rapid heating step was chosen to obtain either a recovered or recrystallized condition and thereby to control the distribution of residual deformation defects, which in turn influenced the size and distribution of α precipitates in the final microstructure. It was established that a good balance of high strength (in excess of 1600 MPa) and reasonable ductility could be obtained if a fine-grain microstructure with a β grain size of ∼10 μm was formed by recrystallization. The development of such a fine-grain size enabled a reduction in the aging temperature and thus increased the strength while maintaining ductility within the desired limits. In this respect, the properties could be varied to a great extent by varying the rate of heating to the aging temperature. On the other hand, aging of the recovered condition also led to a strength level of approximately 1600 MPa but with generally lower ductility than in the fine-grain, recrystallized condition. Another distinctive feature of the recovered condition was that the properties were relatively insensitive to the rate of heating to the aging temperature.},  number = {1–2},  urldate = {2015-10-08},  journal = {Journal of Alloys and Compounds},  author = {Ivasishin, O.
