Partitioning of elastic distortions at a semicoherent heterophase interface between anisotropic crystals

abstract

Bicrystals containing semicoherent interfaces exhibit distortions produced by the superposition of coherency strains and the elastic strain fields of interface Volterra dislocations. Using an approach that combines the quantized Frank-Bilby equation with anisotropic elasticity theory, this residual elastic state is computed for semicoherent heterophase interfaces formed by face- and body-centered cubic crystals. Elastic distortions are found to be unequally partitioned between the neighboring anisotropic materials. For any given heterophase interface, these distortions determine the coherent reference state within which the Burgers vectors of the interfacial dislocations are defined.
