Abstract (en)
[origin: EP0419789A1] The invention relates to a shape memory alloy for repeated applications, which contains no noble metals. <??>NiTiZr and NiTiZrCu shape memory alloys whose As temperature is above 100 DEG C are described. Such shape memory alloys have the following composition: 41.5 to 54 atom % of Ni, 24 to 42.5 atom % of Ti and 7.5 to 22 atom % of Zr and optionally up to 8.5 atom % of Cu.
