The influence of d-band structure on stacking-fault energy

Abstract

Abstract The variation of stacking-fault energy across the alloy systems, Cu-Ni, Cu-Pd and Ag-Pd respectively has been estimated by a texture method based on the dependence of cross-slip on the stacking-fault energy. The variations with composition have been correlated with known changes in the electronic specific heats and magnetic susceptibilities of these alloys. It is concluded that the presence of empty d-states in these alloys results in a large increase in the stacking-fault energy.
