Using single-crystal Ni 54 Fe 19 Ga 27 (at.%) specimens, the effects of heat treatment, annealing at the temperatures within T = 473–1473 K for one hour followed by quenching into water, on the development of thermoelastic L21-L10 martensitic transformations is investigated. It is found out that using proper heat treatment modes one can control the temperature of L21-L10 martensitic transformations, the value of the temperature hysteresis, the critical stresses of twin boundary motion, and certain functional properties of single-crystal Ni-Fe-Ga.
