Resumen:
We report fully three-dimensional atomistic molecular dynamics studies
of grain growth kinetics in nanocrystalline Cu of 5 nm average grain
size. We observe the formation of annealing twins as part of the grain
growth process. The grain size and energy evolution was monitored as a
function of time for various temperatures, yielding an activation energy
for the process. The atomistic mechanism of annealing twin formation
from the moving boundaries is described.
