抄録

The transition phase, ω, which is formed during the transformation β⁄β+α makes the alloys very hard and brittle. This ω phase was investigated by transmission electron microscopy in the Ti-Mo (β isomorphous type) and the Ti-Mn (β eutectoid type) system. The ω phase in Ti-Mo alloys is ellipsoidal with a major axis parallel to ⟨111⟩β, its maximum size being about 2000 Å. On the other hand, the shape of the ω phase in Ti-Mn alloys is cubic with a habit plane {100}β, its maximum size being about 300∼350 Å. The ω phase in the quenched material (ω′) of Ti-Mo alloys is formed more easily with the decrease of solute atom contents and extends in the form of a very fine needle parallel to ⟨111⟩β.
