  1. ; (, Materials Characterization)
    In this paper we apply the concept of the Clifford torus and the derived square torus maps to the study of disorientations in microstructures. First, we interpret the Clifford torus in terms of the more commonly used orientation representations (Rodrigues-Frank vectors, 3D stereographic vectors, and homochoric vectors) and show representations of the torus in those spaces. This leads to a simple graphical interpretation of the generation and meaning of the square torus maps. Then we apply this approach to the study of disorientations in polycrystalline materials (CSL boundaries in grain boundary engineered Nickel) as well as intervariant boundaries in martensitic and bainitic steels. We show that pre-computed theoretical square torus maps can be used to determine population fractions of specific boundaries.
