Textural control of BCC/HCP two phase Magnesium alloy with the β-Sc phase

镁合金的传统工艺是HCP Mg相的固溶硬化或沉淀硬化。因此，在这项工作中，我提出了一种新的β- sc相两相镁合金。通过扩散偶和透射电镜观察对相图进行了重新评价。我发现β-Sc相存在于Sc含量较低的15at%Sc中。通过铸造，在Mg-22at%Sc中获得了良好的两相织构。与传统镁合金相比，该合金具有更好的强度-延性平衡。

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.
