Mg alloys have been attracting considerable attention for next generation structural materials for long time because of their high specific strength. However, conventional Mg alloys have been used only in a limited field because of their poor formability, which arises from limited slip-systems of hcp structure. Among binary Mg-X systems, only Mg-Li and Mg-Sc alloys have a bcc structure in a Mg rich composition. Mg-Li alloys with bcc/hcp dual-phase is reported to show a high elongation. However, Mg-Li alloys possess lower tensile strength and poorer corrosion resistance than conventional Mg alloys. Recently, our group have focused on Mg-Sc alloy and found that Mg-Sc alloy with bcc/hcp dual-phase shows much higher tensile strength than Mg-Li alloys. In this presentation, we will discuss on the relationship between mechanical properties and microstructure in Mg-Sc alloys.
