Abstract

Using severe plastic deformation (SPD) by HPT and ECAP we have produced nanostructured TiNi shape memory alloys with grain size near 100 nm and smaller. This paper presents the results of the first studies of phase and structure transformations in SPD-processed nanostructured TiNi alloys during cooling and heating. New mechanisms of thermoelastic martensitic transformations in the SPD nanostructured alloys are revealed and their critical temperatures are determined. It is shown that use of SPD lead to change in the temperatures of martensitic transformations in B2 TiNi alloys, and to enhancement in their mechanical properties.
