Metastable austenitic stainless steel is transformed to martensitic phase from austenitic phase by strain of cold working. This phenomenon is called strain induced martensitic transformation and brings high ductility, high strength. In this study, we performed quantitative analysis of strain induced martensitic transformation by X-ray diffraction. In addition, we did to investigate the relation between volume fraction of martensite and crystal lattice plane. The present result suggested that quantitative analysis is involved two Bragg peaks that were used for the analysis, and provided that the two surface directions of crystal lattice planes resulting from the Bragg peaks are near, the volume fraction of martensite is large. It is surmised that rotation of the crystal grain accompanied by strain is related to this result.
