Experimental investigation the interaction between phase and structure deformations in shape memory alloys

, ,

Abstract:

Experimental study is carried of the direct martensitic phase transformation strain accumulation processes in NiTi samples after rolling with a 0.7 logarithm strain degree. The experiments are carried on the martensite inelasticity strain accumulation with the same samples as well. It was found that direct transformation diagram is on the stress – strain plane between martensitic inelasticity diagram and the strain axis. The results of experiments are described in which the first step is a direct phase transformation, and the second – the structural transition.
