Abstract:
Nano-Twinned (NT) Cu under shock loading parallel to twin planes was investigated via nonequilibrium molecular dynamics (NEMD) simulations, with particular attention to the shock response and intrinsic deformation mechanism. During the shock compression process, a novel multi-stage phase transformation (MPT) scenario happens due to shock-enhanced twin boundary (TB) sliding. These new results have great potentials for improving the impact resistance of metals by tailoring their internal nanostructures.
