摘要： Ferrous group shape memory alloys consisting essentially of Cr: 16.0-21.0 wt %, Si: 3.0-7.0 wt % and Ni: 11.0-21.0 wt % and satisfying Ni wt %.gtoreq.[0.67.times.{Cr+1.2.times.(Si+Ti+Zr+Hf+V+Nb+Ta)}-] wt % and (Cr+Si) wt %.gtoreq.20 wt %, these ferrous-group shape-memory alloys having a corrosion resistance, a shape-memorizing properties, an intergranular corrosion resistance and a stress corrosion cracking resistance in nitric acid for nuclear fuel reprocessing plants and high-temperature, high-pressure water for light-water reactors.
