Abstract
Recent experimental studies on nanocrystalline metals have shown that mechanical strength may decrease with decreasing grain size d for d7 nm) to localized grain boundary migration (d<7 nm). Thus, these data suggest that both the onset and mechanisms of plasticity in nanocrystalline materials change markedly below a critical grain size. (C) 2003 American Institute of Physics.
