Research Abstract

Yielding of polycrystalline ductile materials can be realized by transfer of dislocation across a grain boundary (GB), or by incorporation between the residual GB dislocation and the dislocations nucleated in the near-field of GB due to the applied stress. These phenomena are determined by the crystallographic orientation and the multiaxial stress state around GB. In the present research, the interaction between dislocations and GB among several defects interactions has been investigated from nanoindentation using a micro-sized pillars consisting of two grains and one GB. Also molecular dynamics simulations revealed the physical dislocation reactions under a uniform compression and a nonuniform indentation stress state.These interactions can be summarized by using a boundary interaction condition proposed here.
