The lattice dislocation trapping mechanism at the ferrite/cementite interface in the Isaichev orientation relationship

Abstract We analyze the lattice dislocation trapping mechanism at the ferrite/cementite interface of the Isaichev orientation relationship by atomistic simulations combined with the anisotropic linear elasticity theory and disregistry analysis. We find that the lattice dislocation trapping ability i...
