EFFECT OF γ-IRRADIATION ON CuZnAl SHAPE MEMORY ALLOY

Effect of γ-irradiation on the shape memory alloy CuZnAl has been studied by the techniquesof TEM,positron annihilation etc..The martensitic transformation temperature of the alloyincreases 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.
