Fig.3 Volume fraction (a) and transformation rate (b) of α'-martensite versus temperature in pre-deformation and undeformed 321 stainless steel samples during cryogenic treatment (Ms1 and Ms2 are the martensite transformation start temperature(Ms) of undeformed and pre-deformation samples, respectively. Stages I, II, and III represent the transformation start, fast transformation, and transformation saturation, respectively)
