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

摘要

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.
