  超细化
     An Ti-12Co-SAl alloy sheet with an ultra fine α-Ti/Ti2Co microstructure was prepared by proper smelting and thermomechanical treatment. An excellent superplastic elongation more than 2000% was obtained at high strain rate of3 ×10-2 s-1 and under relatively low temperature of 700℃. Microstructural study indicates that the supepolastic defomration promotes the grain growth and shape change of the Ti2Co intermetallic particles.

Microstructural study indicates that the supepolastic defomration promotes the grain growth and shape change of the Ti2Co intermetallic particles.No cavity was found in the specimen after even superplastically deformed to 1550%. The combination of strain hardening, resulted from the coarsening of α-Ti grains and Ti2Co particles, together with the strain rate hardening is considered to be the main reason why the alloy exhibits excellent superplasticity.
