Texture of hot rolled and annealed binary Ti-Mn alloys

This work describes the development of texture during hot rolling and annea ling of two binary Ti-Mn alloys. The alloys Ti - 0.4Mn (alpha -type) and Ti - 1.8Mn (near a-type) have been unidirectionally rolled up to 70% reductio n at 750 degreesC, and air-cooled. The samples taken from these hot rolled plates were subjected to isothermal annealing at 700 degreesC for different lengths of time. After hot rolling, Ti-0.4Mn shows nearly a c-type texture , and Ti- 1.8Mn an R-type texture. Annealing of the Ti-0.4Mn alloy generate s a T-type texture, whilst annealing of the Ti-1.8Mn alloy leads to a conti nuous change in the hot rolling R-type texture. These results are compared with hot rolling and annealing textures of titanium and its alloys.
