Growth Selection in High Purity Cadmium
Growth selection studies have been performed with 99.9999% cadmium and a cadmium-5 atom p.p.m. lead alloy. After severe local deformation single crystals of a standardized orientation were annealed resulting in the recrystallization of the heavily deformed region, and the competitive growth of these recrystallized grains down the strain gradient into the single crystal matrix. A three dimensional orientation space has been employed to describe the distribution of selected orientations. and six preferred orientations have been identified. The relative preference for these preferred relationships is shown to be dependent on the single crystal orientation, the solute concentration and the annealing temperature.
