Abstract

The work is devoted to the study of the processes of hot and cold plastic deformation of hard-to-deform shape memory alloys of the Ni–Ti–Nb and Ni–Ti–Nb–Zr systems. The optimal modes of deformation treatment of these alloys, which ensure the production of semi-finished products without surface defects, have been determined. Investigations of the mechanical properties of hot-deformed and cold-deformed semi-finished products from alloys of the Ni–Ti–Nb and Ni–Ti–Nb–Zr systems have been carried out. It is shown that the selected treatment modes of these alloys provide a high level of mechanical properties of materials.
