Abstract
For the first time Ni44Fe19Ga27Co10 single crystals with high-temperature martensitic transformation (Ms = 336 K) and high-temperature superelasticity (373–548 K) under tension and compression were obtained after annealing at 1448 K for 6 h, followed by fast quenching in ice-cold salt water. The increase in temperature is associated with the precipitation of the large γ-particles and the substantial decrease in the precipitation of the nanosized ω-phase, which was observed in the single crystals after annealing at 1448 K for 1 h with slower water quenching.
