The influence of the combined action of severe plastic deformation (SPD) and pulse current on the microstructure and mechanical behaviour of TiNi alloys in austenitic and martensitic states is investigated. The dependence of the electroplastic effect on the initial phase composition of the alloys is demonstrated. It is established that electropulse treatment (EPT) after SPD promotes the acceleration of stress relaxation during recovery, polygonization and recrystallization of deformed TiNi alloys.
