摘要:
Nanopowder consolidation under high strain rate shock compression is a potential method for synthesizing and processing bulk nanomaterials, and a thorough investigation of the deformation and its underlying mechanisms in consolidation is of great engineering significance. We conduct non-equilibrium molecular dynamics (NEMD) simulation and X-ray diffraction (XRD) simulation to systematically study shock-induced deformation and the corresponding mechanisms during the consolidation of nanopowdered Mg (NP-Mg). Two different deformation modes govern...
