中文摘要	The pseudo-quaternary Heusler alloys Co(50) Ni(22) Ga(28) : Fe(x) ( x = 0, 1. 5. 2, 2. 5) single crystals have been synthesized. Excellent pseudoelasticities were observed in compression, bending and torsion. At room temperature, the perfect pseudoelastic strains of 4% and 6.7% were obtained in the [100] and [110] directions of the Co(50)Ni(22) Ga(28) : Fe(2) single crystal under compression, respectively. The stress-strain curve for the Co(50)Ni(22) Ga(28) : Fe(1.5) single crystals shows an indistinct platform on loading, and an intermartensitic transformation occurs with unloading. The platform of the curve on loading becomes clear and the intermartensitic transformation with unloading becomes indistinct at the high temperature of 100 degrees C. Pseudoelastic strains of 5. 5% were obtained in the [001] direction of the Co(50) Ni(22) Ga(28) : Fe(2.5) single crystal. In addition, the single crystals show strong elastic anisotropy.
