Translated title of the contribution: Proposal of the parameters CH00 and Q required in the modified Williamson-Hall method

Research output: Contribution to journalArticle


In the modified Williamson-Hall method, the parameters Ch00E, Ch00S, qE and qS play an important role to determine the dislocation character. These parameters are obtained from elastic stiffness c11, c12 and c44 but the values of elastic stiffness are sensitive against the data of Young's modulus in poly-crystal. Young's modulus of poly-crystal is changeable depending on the texture and this causes some confusion on the calculated results for the parameters Ch00E, Ch00S, qE and qS. In this paper, reliable values are proposed for Ch00E, Ch00S, qE and qS in aluminum, copper, nickel, bcc-Fe and fcc-Fe.
