Development of High-Performing Extruded Magnesium Alloy

Abstract:

To develop high-performing extruded magnesium alloys, we had investigated the effect of zinc into Mg-5Gd-2Y-xZn-0.7Ca (x = 1, 2, 3, and 4) alloys. With increasing of zinc content up to 3 wt.%, the volume fraction of LPSO phases and strength increased, while the volume fraction of LPSO and strength rapidly decreased when zinc content was 4 wt.% in Mg-5Gd-2Y-xZn-0.7Ca alloys. Ignition temperature and corrosion rate were directly proportional to the increase of zinc content in this study. The optimum zinc content was 2 wt.% in Mg-5Gd-2Y-xZn-0.7Ca alloys and VWZO52207 alloy exhibited high strengths (TYS: 407 MPa and UTS: 424 MPa), adequate elongation (6.9 %), and high ignition temperature (934 ^oC).
