Abstract
⺠The corrosion properties of three Fe-Mn-Si-Cr-Ni-(Co) shape-memory stainless steels (SMSSs) were compared with those of a type 304 (SS 304) austenitic stainless steel. ⺠A considerably high Si content (about 40 at%) is present in the anodic passive films formed on SMSSs in 0.5 M H2SO4 solution. ⺠The high protectiveness of the anodic passive film formed on SMSSs in 0.5 M H2SO4 solution results from a protective film consisting of a (Fe, Cr)-mixed silicate. ⺠The SMSSs exhibited higher corrosion resistance than SS 304 in highly oxidizing environments. ⺠The SMSSs showed poor corrosion resistance in 3.5% NaCl solution compared to that of SS 304.
