Outline of Final Research Achievements

Inverse Self-consistent (iSC) and inverse Voigt-Reuss-Hill (iVRH ) approximations which can determine the elastic constants of single crystals from those of polycrystals were applied to pure Mg polycrystals prepared by an extrusion process, and the validity of the approximation methods was clarified. Furthermore, the iSC approximation was applied to an Mg-3 mass% Zn-1 mass% Al polycrystal, whose single crystal is difficult to grow, and its single-crystalline elastic constants were determined. In addition, an Mg-44 mass% Al alloy (Al12Mg17 compound) single crystal was grown and its elastic properties were measured using resonant ultrasound spectroscopy combined with electromagnetic acoustic resonance.
