Abstract

There were studied some mechanical properties of TiNi (50.6 at. % Ni) shape memory aloy, using dynamic mechanical analysis and tensile tests. The aim of our studies was to point out a correlation between the mechanical behaviour and the martensitic transformation of the a loy during heating/cooling process. A difference between stabilization of the mechanical properties and the martensitic transformation was observed. The heat treatment parameters necessary for inducing the shape memory effect or the superelasticity of the aloy are, also, presented in this paper..
