形状记忆合金及其应用

Shape Memory Alloy and Its Application

介绍了一种新型功能材料——形状记忆合金,包括其发展过程和应用水平。阐述了这种合金随温度变化而呈现出的奇特的形状记忆效应及该材料结构的特殊性能;国内外关于这种合金的研究、开发、应用和展望;提出适合特殊用途的几种新型记忆合金。

A new kind of functional material-shape memory alloy (SMA) is introduced,including the course of its development and the level of its application. The unique ability of SMA' s changing its own shape with the change of temperature——so called shape memory effect and some special property are presentedtoo. Research,exploitation,application and prospect with regard to SMA at home and abroad are also referred. At last some new memory alloys fit for special proposes are come up with.
