Description
Summary:This is a comment on the paper Materials Science & Engineering A 826 (2021) 141960 titled ʺInfluence of prior deformation temperature on strain induced martensite formation and its effect on the tensile strengthening behaviour of type 304 SS studied by XRDLPAʺ. It is shown here that the methodology used for the determination of the dislocation density from the X-ray diffraction peak breadth was not correct. This study reveals that the dislocation density obtained from the breadth of the diffraction profiles may significantly deviate from the reliable values determined by pattern fitting method.
