α Phase Forming on Surface Layer and Precipitating inside of a Ti-Mo Based Alloy Annealed in Air
α-phase forming on the surface layer and precipitation of α-phase inside a Ti-Mo alloy during annealing in air has been investigated thermodynamically. α-phase layer is increased rapidly when annealing temperature exceeds 700°C. When the 850°C solution-treated specimen annealed at 400°C for 1 hour, there is no α-phase precipitates. As annealing temperature increased to 800°C, the amount of α-phase precipitates first increased to a maximum at 600°C, then decreased.
