Features of nanostructure and functional properties formation in Ti-Ni shape memory alloys subjected to quasi-continuous equal channel angular pressing

Abstract

Influence of various deformation regimes, included severe plastic deformation by multi-pass rolling, rotary forging and equal channel angular pressing (ECaP) in the normal and quasi-continuous modes, on the structure and properties of Ti-Ni shape memory alloys was studied and compared. Features of structure formation providing a combination of high functional properties were analyzed. Investigation of the texture development, depending on the ECAP regimes and post-deformation annealing, was made.
