| Research Abstract |
Conventional progress of Mg alloys is the solution or precipitation hardening in HCP Mg phase. So, in this work, I suggested the new two-phase Mg alloy withβ-Sc phase. I reappraised the phase diagram by diffusion couples and TEM observation. And I found that β-Sc phase exists in the lower Sc content at 15at%Sc. The fine two-phase texture is obtained in Mg-22at%Sc by casting. This alloy has more excellent in balance of strength-ductility than conventional Mg alloys.
