Abstract

One of the prospective methods for structure refinement is electroplastic rolling (EPR). The use of an electric current pulse during cold rolling enhances deformability (1.5-3 times for TiNi-based alloys). It was shown that EPR (e > 1) with post-deformation annealing at 450-500 °C leads to nanostructure formation with a grain size of 60-120 nm. Also, EPR leads to an increase in functional properties of TiNi-based alloys. So, the recovery coefficient was revealed as being better than the undeformed alloy (90-96% for Ti49,2Ni50,8 and 75-80% for Ti50,0Ni50,0). In the Ti50,0Ni50,0 subjected to EPR up to strain 3.6 and subsequent annealing at 450 °C for 1 h, the superelasticity effect is found.
