Abstract

Authors have published a number of papers on asymmetric X-ray line broadening in tensile deformed [001]-oriented copper single crystals. However, when comparing crystals, tensile-deformed up to about the same shear stress one of the authors, H. Mughrabi found internal stresses which are smaller than those reported earlier by a factor of about 2. This discrepancy led them to reconsider the corresponding scaling factors in the former papers. Indeed, an error by a factor of 2 was found when converting the separation of profiles into long-range internal stresses. Accordingly the changes are suggested in earlier papers.
