摘 要: 测定了Cu-12.2Al-4.0Mn形状记忆合金的塑性图,研究了微量元素Ni,Co和B对合金的显微组织和加工性能的影响。结果表明:1)试验合金在700℃~800 ℃高温β 相状态下具有非常好的塑性加工性能,而在室温则呈脆性断裂;2)试验合金中加入少量的(Ni+B+Co),可以细化合金的晶粒,提高合金的冷加工性能;3)采用有利发挥合金塑性的加工方法,则能提高该合金的冷加工性能。

Abstract:  A plastic graph was surveyed and the effect of trace elements such as Ni, B and Co on microstructures and working properties of Cu -12.2Al-4.0Mn shape memory alloy was studied. The test results are as follows: 1)The alloy possesses excellent plastic working properties in β phase state at 700~800   ℃, but it occurs brittle breakdown at room temperature; 2 ) Grain was refined and cold workability increased with adding trace elements such as (Ni+B+Co) into the alloy; 3) When the process of favorable heightening technical plasticity of alloy is selected, the cold working performance of the alloy will be enhanced.
