Abstract

The superelasticity of alloys undergoing a stress-induced martensitic transformation is studied in both experimental and theoretical way. Experimental stress--strain dependencies illustrating the different types of superelastic behavior are taken from Ni--Mn--Ga alloys typifying thermoelastic martensites and then modeled theoretically using a statistical approach to describe the growth of stress-induced martensite in the matrix of parent (austenitic) phase. A good agreement between the experimental and theoretical results is achieved whereby a physical interpretation of the different types of stress--strain dependencies is made and a quantitative evaluation of the main parameters controlling transformational behavior of the alloys is carried out.
