Abstract

X-ray diffraction line profile analysis(LPA)assesses dislocation status, which is highly correlated with mechanical properties. In addition to dislocation density, a measured line profile contains information such as crystallite size, dislocation character, and dislocation arrangement parameters, which can be analyzed by the LPA. In particular, dislocation density significantly impacts metallic materials'mechanical properties, such as yield stress. Examples of research examining the relationship between its quantification and mechanical properties are presented. We also provided an example in which the dislocation structure formed by plastic deformation can be characterized by parameters other than the dislocation density.
