Abstract: The capability of damping mechanical energy in polycrystalline metals depends on the activities of defects such as dislocation and grain boundary (GB). However, operating defects has the opposite effect on strength and damping capacity. In… read more here.

DOI: 10.1021/acs.nanolett.9b05202
Abstract: Conventional polycrystalline metals become stronger with decreasing grain size, yet softening starts to take over at nanometer regime, giving rise to the strongest size at which the predominate strengthening mechanism switches to softening. We show… read more here.
