抄録

Elongation in the tensile test and reduction of cold rolling to failure of Mg-Li and Mg-Zr-Li alloys were investigated. Grain size of α range alloys cast in the same condition was decreased with increasing lithium and the workability of magnesium was improved by the addition of lithium. More uniform deformation and higher rollig reduction to producing deformation band were obtained in the lithium containing magnesium alloys than in pure magnesium. The microcracks were observed in the deformation band. The ductility of magnesium was remarkably improved by the small addition of zirconium. Binary and ternary alloys consisting of (α+β) two phase were extremely superior in ductility to the single α or β phase alloys. It was confirmed that the spheroidizing treatment of the eutectic structure resulted in the improved workability.
