ATOMISTIC MODELING OF DISLOCATION-INTERFACE INTERACTIONS

摘要：

Using atomic scale models and interface defect theory,we first classify interface structures into a few types with respect to geometrical factors,then study the interfacial shear response and further simulate the dislocation-interface interactions.The results show that the structural characteristics of both heterophases and homophases interfaces play a crucial role in (i) their mechanical responses and (ii) the ability of incoming lattice dislocations to transmit across them.
