| Outline of Final Research Achievements |
An inverse self-consistent (iSC) approximation that can extract the elastic constants of single crystals from those of polycrystals, taking into account the elastic interaction between the grains, was newly developed. Also, inverse Voigt-Reuss-Hill (iVRH) approximation that can determine the elastic constants of single crystals with various crystal structures from those of polycrystals was developed. To examine the validity of iSC and iVRH approximations, they were applied to Cu polycrystals prepared by a directional solidification method, and the validity of the developed methods was confirmed. Furthermore, in Ti-Nb-based alloy developed for biomedical applications, the elastic properties of single crystals in which ω phase or diffuse ω structure were formed within the β phase were clarified.
