The temperature interval ΔT SE of superelasticity in -, -, and -oriented Co40Ni21Ga30 (at. %) single crystals strained at compression has been studied. It is established that ΔT SE in the -oriented single crystal amounts to 441 K and the reversible B2-L10 martensite transformations in loaded samples take place at T 2 = 698 K. In - and -oriented samples, ΔT SE decreases to 233 K and the superelasticity is observed up to T 2 = 523 K. © 2009 Pleiades Publishing, Ltd.
