Transformation microstructures in a Ti-31A1-13Mo alloy

Some initial results are presented on the formation of the y phase, based on the intermetallic TiA1 (LIo, c/a = 1.02) from the phase, based on the intermetallic TidAl (DOts , c/a = 0.801) in a Ti-31wt. Al-13wt Mo alloy. The study is part of a programme to evaluate microstractures and properties of alloys containing the y phase in the Ti-Mo-AI ternary system.
