摘要
介绍了两种Cu -Al-Mn形状记忆合金 ,测量其马氏体转变温度 ,发现 9R马氏体结构的合金相变滞后宽度远大于 18R 马氏体结构的合金。用于管接头 ,由于形状记忆效应 ,起到紧固连接作用 ,是具有工业应用前景的新材料。
Two kinds of Cu-Al-Mn type memory alloys are described.Through the measurement of their martensitic transformation temperatures,it is found that the phase change lag width of the alloy with 9R martensitic structure is far greater than that of the alloy with 18R martensitic structure.When they are used in pipe joint,their type memory effect can function as securing the connection.Therefore,they are new materials that have industrial application prospect.
