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.

镁合金的常规进展是HCP Mg相的固溶或沉淀硬化，因此，在这项工作中，我提出了通过扩散偶和TEM观察来重新评估具有β-Sc相的两相镁合金。研究发现，在 15at%Sc 含量下，β-Sc 相存在。通过铸造，Mg-22at%Sc 合金具有更优异的强度-延展性平衡。镁合金。
