This work presents the effect of stress-induced martensite aging (SIM-aging) on the functional properties of Ni 53 Mn 25 Ga 22 (at.%) single crystals, oriented along the [001] L21 -direction. The most effective regime of SIM-aging occurred under a compressive stress of 175 MPa along the [110] L21 ||[100] L10 -direction at 423 K, for 2 h, which induced the high-temperature two-way shape memory effect with a reversible tensile strain of +9.0%, causing the jumping of the sample during cooling/heating in free state, and a rubber-like behavior with a giant reversible compression strain up to − 13.2% caused by L1 0 -martensite variant reorientation.
