形状记忆合金作为一种智能型功能材料，自1962年首次获得应用以来，在众多相关领域得到了越来越多的关注和应用。 Cu基形状记忆合金以其良好的形状记忆性能、优秀的导电导热性能、相变温度可调范围宽以及价格低廉等诸多优点，成为具有重要发展潜力的一类形状记忆合金。近几年，智能系统的迅速发展和高性能Cu基形状记忆合金的开发较大的推动了Cu基形状记忆合金的应用。综述了近5年Cu基形状记忆合金在交通运输、机械制造、土木建筑、生物医疗等方面的最新应用实例，并对其未来发展方向进行了展望。
Shape memory alloys ( SMAs) , as a kind of intelligent functional materials combining with perception and driv-ing function, are more attention to and widely used in various fields since the first application in 1962. Cu-based SMAs are the most potential ones for large-scale industrial applications because of their good shape memory properties, high electrical and thermal conductivities, wide-range transformation temperature and low cost, etc. In recent years, the applications of Cu-based SMAs are booming with the rapid developments of the intelligent system and high performance Cu-based SMAs. This paper reviewed the typical applications of Cu-based SMAs in recent five years in transportation, machinery, civil construction, biomedical devices, etc. Finally, the future development for Cu-based SMAs was also discussed.
