The purpose of the present work is to improve the elongation of the b.c.c. single phase Mg-Li-Al alloys by the addition of the fourth alloying element. As the fourth alloying element, the authors have chosen copper because it is slightly soluble in magnesium and is expected to act as the nucleation sites for precipitates in this alloy; many nucleation sites for the precipitates are introduced into the Mg-Li-Al alloy so that the precipitates particles are finely and uniformly dispersed. Hence, it is expected that a good combination between high tensile strength and high elongation is obtained. The authors have investigated the relationship between aging behavior and the mechanical properties of the Mg-37.5 at%Li-0.7 at%Al-0.4 at5 Cu alloy.
