Influence of Cooling Rate on the Deformation Processes Associated with Direct Martensitic Transformation in TiNi Alloy

Elisey A. Khlopkov, Yuriy N. Vyunenko

Abstract. The influence of cooling rate on the mechanical characteristics of metals with shape memory is mentioned in connection with the dissipative properties of this materials class. This paper presents the different cooling rate regimes research results of ring-shaped force elements demonstrating the possibility of this parameter influence on their deformation characteristics in the temperature range of direct martensitic transformation.
