Abstract
The loss of coherency across a two‐phase interface was studied by invoking a dislocation model of the two‐phase interface. In particular, the interface consists of periodically arranged misfit dislocations with interface dislocations distributed in between the misfit dislocations. A coherent interface consists of uniformly distributed interface dislocations and becomes noncoherent by rearrangement of the interface dislocations. This rearrangement of interface dislocations was studied by the techniques of continuously distributed dislocations and by the method of discrete distributions of dislocations. The atomic step produced across the interface is related to the physical properties of the two phases and to the magnitude of the frictional stress across the interface.This publication has 4 references indexed in Scilit:
