Due to its low specific mass and high strength at high temperature, γ-based Ti-Al alloys are candidate materials for use in aerospace industries. Due to its simple structure, polysynthetically twinned (PST) Ti-Al alloys are excellent candidates for in-depth studies. The superior properties of Ti-Al alloys render them more suitable for applications in the automobile and aerospace industries compared to conventional Ni based super-alloys. The potential of using these alloys for the manufacture and application of dedicated and advanced components in these industries provided the driving force for the present study.
