Abstract

In texture analysis measured orientations are frequently represented in the Euler space. To detect special orientations (hkl) [uvw] use can be made of plane sections (Euler angle φ₂ = const) through the Euler space. Orientation relationships appear as points in these “maps.” For texture analysis the points are plotted in maps for cubic crystals in an orthorhombic specimen. In this paper similar maps are proposed to detect special orientation relationships between neighbouring grains in a polycrystal. These maps, based on the symmetry of the Euler space resulting from the cubic symmetry of both crystal neighbours, are discussed and their handling is demonstrated using measured orientation relationships in single and dual-phase brasses.
