摘要：

The evolution of the microstructure and the change in the martensitic transformation temperatures of the Ti49.2Ni50.8 (at.%) alloy with increase of the magnitude of deformation upon isothermal rolling in channel rollers (T = 723 K) have been investigated. It is found that the grain size grows in the initial stages of deformation. It has been shown that for e > 0.2 a change in the grain structure takes place over the entire bulk of the specimen via the mechanism of continuous dynamic recrystallization. It has been established that up to a deformation of e similar to 0.2 the martensitic transformation temperatures vary nonmonotonically and remain practically constant thereafter, which is explained by the occurrence of processes of dynamic recrystallization.
