Effect of γ-irradiation on the shape memory alloy CuZnAl has been studied by the techniques of TEM,positron annihilation etc..The martensitic transformation temperature of the alloy increases obviously ofter γ-irradiation at a dose of 2×10~7 Gy but not for a dose of 1× 10~7 Gy.The shape memory effect in both irradiated alloys remains unaffected.
