| Outline of Final Research Achievements |
Pure shear tests were carried out to evaluate critical resolved shear stresses (CRSS) of hexagonal close packed metals. As a result, the CRSSs for the basal slip of pure magnesium and for the prismatic slip of pure titanium were close to conventional value. This indicates validity of the pure shear test method developed in this study. By using magnesium single crystals, CRSSs of first order pyramidal slip, second order pyramidal slip and {10-12} twin were estimated. CRSSs of second order pyramidal slip and {10-12} twin were similar to that of tensile tests. For first order pyramidal <c+a> and <a> slips, the CRSSs were obtained from experimental date and finite elemental method.
