Abstract

This work applies a constrained coincidence site lattice/constrained complete pattern shift lattice (CCSL/CDSCL) model and secondary O-lattice model to simulate the interfacial structure in the major side interface of Mg17Al12/Mg. The result shows that, at the orientation relationship (OR) with a small deviation (∼0.5 deg) from the Burgers OR, the secondary misfit in the interface normal to the parallel Δg vectors can be completely accommodated by the steps. The secondary dislocation networks in the habit plane and major side facet have been calculated.
