Orientation relationships between the parent and the product phase are essential for understanding the crystallography and for building predictive models of microstructure evolution during phase transformations. Experimentally observed orientation relationships usually correspond to transformations that generate a plane with minimal interfacial energy and lattice strain across the adjoining phases. Hence, a simple algorithm generating the Near-Coincidence Site Lattices for the heterophase interfaces will provide a powerful tool in predicting such orientation relationships. Grimmer, in a series of articles, has proposed the generating functions for determining the coincidence site lattices for homophase interfaces (grain boundaries) of cubic, hexagonal, trigonal and tetragonal Bravais lattices. These generating routines become increasingly complexity as the underlying symmetry of the lattice is reduced. In this talk, I will present a simple algorithm for computing near-CSL rotations between any two Bravais lattice systems (i.e. both homo-phase and hetero-phase interfaces).
