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