Deformability and structural features of shape memory TiNi alloys processed by rolling with current

It is shown that the deformability of Ti49.2Ni50.8 and Ti50.0Ni50.0 alloys rolled with electric current is considerably greater than that obtained by cold rolling. The influence of deformation with an electric current on features of the microstructure was investigated. The intensity of strain hardening was compared for both alloys after electroplastic rolling (EPR). The reasons for the different behaviors in the EPR process are discussed.
