目前实用的形状记忆合金有ＮｉＴｉ、Ｃｕ－Ｚｎ－Ａｌ和Ｃｕ－Ａｌ－Ｎｉ合金，其应用温度范围都在室温至２００℃以下，都不能在较高的温度下使用。本文作者开发了新一类高温形状记忆合金，它们是近于等原子成分的钽－钌合金和铌－钌合金，这类合金具有高于１０００℃的形状
At present, the practical shape memory alloys are NiTi, Cu-Zn-Al and Cu-Al-Ni alloys, and their application temperature range is from room temperature to below 200 DEG C and can not be used at higher temperatures. The authors have developed a new class of high temperature shape memory alloys that are near-isotopic tantalum-ruthenium alloys and niobium-ruthenium alloys that have a shape above 1000 ° C
