In order to study the affects of $\alpha$ formation test should be conducted on titanium alloys with varying $\alpha$ stabilizer content and testing what the optimal level of stabilizer are suitable to nucleate desired $\alpha$ content. The affects of the duration of aging as well as temperature of aging should also be studied and a comparison should be made between alloys. The affect of continuous $\alpha$ formation at the boundaries should also be studied. As written in the understanding section that although having $\alpha$ at boundaries may cuse cracks the same phenomena is responsible for higher dislocation density, which increases strength. It is also necessary to use better technology to pin point the location of $\alpha$ formation. It would also be useful to study titanium alloys with lower number of alloying elements so that the effects of each element on the formation of $\alpha$ particles can be noticed without possible interference of other elements in the composition.  Both mechanisms however increase the dislocation density in the matrix therefore alloys experience dislocation hardening. Other methods of increasing strength include:  Other impurities- Titanium alloys are stronger than pure metals because alloying elements not only stabilize $\alpha$ or $\beta$ phase but also their presence in solid solution imposes lattice strains on the surrounding host atoms. Presence of hydrogen or oxygen Lattice strain field interactions between dislocations and the impurity atoms in restricted dislocation movement making the alloy stronger.  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.
