Proceedings of the International Conference on Martensitic Transformations, ICOMAT-08
Ball & Carstensen [2, 3], theoretically investigated the possibility of the occurrence of non-classical austenitemartensite interfaces and studied the cubic-to-tetragonal case extensively. Here we aim to present an analysis of such interfaces recently observed by Seiner et al.  in CuAlNi single crystals, undergoing a cubic-toorthorhombic: transition. We show that they can be described by the non-linear elasticity model for martensitic transformations and we make some predictions regarding the volume fractions of the martensitic variants involved, as well as the habit plane normals.
