摘　　要：选用几种不同成分的CuAlBe合金,测试了合金在不同热处理状态下的形状记忆效应。结果表明:CuAlBe合金具有较好的形状记忆性能。近共析成分合金记忆性能优于其他合金;正火状态合金记忆性能优于其他热处理状态合金。The effects of composition and heat treatment on shape memory effect of several CuA1Be alloys were studied. The results indicate that the alloy has good shape memory effect. The SME of near eutectic composition is better than other alloys. The SME of normalizing alloys is worse than other alloy. So normalizing alloys obtain good mechanical property.
