Abstract

A reduction in the grain size of a metal offers a means for enhancing the strength by retarding dislocation activity, and at the same time enhancing ductility by processes involving grain boundaries. This overview critically examines various issues relating to strengthening and ductility in nanometals by considering both limitations to strengthening and processes contributing to weakening. It highlights the continuing interesting areas for further research.
