Popis:	The influence of stress-induced martensite aging (SIM-aging, SIM-aged) under compressive load in the [110]B2 direction on the development of thermoelastic martensitic transformation has been studied in single crystals of Ni49Fe18Ga27Co6 ferromagnetic alloy. The experimentally selected effective SIM aging regime (T = 423 K, 1 h, σ = 450 MPa) favors the stabilization of oriented stress-induced martensite and induces a tensile two-way shape memory effect (TWSME) with magnitude of +9.0 ± 0.3% in the [001]B2 direction (perpendicular to the SIM aging load axis [110]B2). The maximum amount of work performed by the crystal under TWSME conditions can reach Wmax = 0.14 J/g (1125 kJ/m3).
