Simultaneous grain boundary migration and grain rotation

The energy of a polycrystalline network can be reduced by both grain boundary migration and grain rotation. We perform a series of molecular dynamics (MD) simulations of a circular grain embedded in an otherwise single-crystal matrix and monitor both the grain size and the misorientation of the two...
