Abstract—The influence of the preliminary direct martensitic transformation in titanium nickelide under a constant compressive stress on the diagrams of subsequent loading under martensitic inelasticity at a monotonically increasing compressive stress is experimentally studied. These diagrams are found to reach the martensitic inelasticity diagram corresponding to the compression of initially fully twinned martensite when the stress increases. The cross hardening on compression is shown to be more intense than that on tension. The phase-structural strain deviator can be considered as a state parameter for a shape memory alloy.
