Abstract

Williamson-Hall (WH) plots in polycrystalline metals are characterized by the irregular arrangement of data due to the elastic anisotropy in each crystal plane. In this study, direct correction of the elastic anisotropy was attempted in WH plots for 30% cold rolled pure iron, pure nickel and an austenitic stainless steel (SUS316L). The results obtained are as follows: 1) Good linearity is realized in the relation between the orientation function H 2 and the inverse of Young's modulus for single crystal and poly crystal (the diffraction Young's modulus). It was found that both lines intersect at H 2 = 0.25 which corresponds to the {110} crystal plane. 2) Using the diffraction Young's modulus ratio which was standardized against that of {110}, the elastic anisotropy in the WH plots was precisely corrected and good linearity was obtained in the corrected WH plots (Diffraction Young's modulus correction method). 3) In the direct fitting method which evaluates the linearity of WH plots with varying Young's modulus ratio, almost same results were obtained as the diffraction Young's modulus correction method.
