Stacking-fault energies can be determined by measuring the positions and profiles of x-ray diffraction lines. Use of this method has been hampered by the uncertainty of the relationship between stacking-fault energy and the ratio of microstrain to stacking-fault probability. Microstrains and stacking-fault probabilities have been determined for five fcc metals by x-ray diffraction line profile analysis. For these metals, Ag, Au, Cu, Al, and Ni, stacking-fault energies have been estimated from a comprehensive updated review of the experimental literature. A linear correlation does exist between γ and 〈ε502〉111/α and thus, the x-ray technique can be applied more confidently. The possible role of elastic anisotropy is also considered.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
