| Abstract Scope |
We describe different facets of the β to α transformation in titanium alloys. with special reference to dominant variant groupings. We then describe two distinct recrystallization processes during thermomechanical processing in the α/β regime with the help of fine scale, orientation image mapping techniques. The first is associated with the well-known α globularisation process. An alternative, dynamic recrystallization process is also observed in which newly recrystallized α and β grains form with the Burgers orientation relationship with each other. We call this process epitaxial recrystallization. We then present the role of transformation and recrystallisation texture on the plasticity of titanium alloys with emphasis on slip length through a quantitative EBSD /TEM based analysis of slip systems in the α phase and slip transfer between the α and β phases. |
