摘要：

X-ray diffraction line profile analyses were used for determination of the dislocation structure of ball-milled copper and iron samples. Plots of integral breadths of the diffraction line profiles in accordance with the classical Williamson-Hall equation clarified stronger strain anisotropy in iron than copper. By the analyses of the integral breadths in accordance with the modified Williamson-Hall equation, the relative fractions of edge and screw dislocations were determined. Prevailing dislocation structure of copper had edge character while those of iron showed mainly screw character.
