Abstract
The effect of extrusion temperature on the mechanical properties of low-Zn containing wrought Mg alloys manufactured by indirect extrusion was studied. The experiments were performed on Mg-Zn-Mn based alloy with addition of LaMM (La rich misch metal). The alloys presented typical bimodal grain structure consisted of large elongated un-DRXed grains and fine recrystallized grains when extruded at relatively low temperature. The alloy showed excellent balance of strength and elongation. The distinct grain structure generated in this study allowed the influence of un-DRXed grains on yield strength to be investigated.
