Abstract

In the modified Williamson-Hall method, the parameters Ch00^E, Ch00^S, q^E and q^S 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 Ch00^E, Ch00^S, q^E and q^S. In this paper, reliable values are proposed for Ch00^E, Ch00^S, q^E and q^S in aluminum, copper, nickel, bcc-Fe and fcc-Fe.
