Abstract

The qualitative experimental results presented here support the hypothesis of Read and Shockly that low angle grain boundaries may not be structurally stable under the action of an applied stress. Our results show that, at least in the constrained geometry of a thin foil, low angle grain boundaries may act as sources for lattice dislocations, eventually causing complete disruption of the structural integrity of the grain boundary.
