Abstract
The mechanisms of plastic deformation of computer simulated nanophase Ni ar e studied for samples with mainly high angle (HA) grain boundaries and with mean grain sizes ranging from 3 to 12 nm, and for samples with mainly low angle (LA) grain boundaries with mean grain size of 5.2 nm. The influence o f the grain size and grain boundary type on the deformation mechanism is di scussed on the atomic level. (C) 1999 Acta Metallurgica Inc.
