Being the lightest materials with high specific strength, magnesium alloys have shown their potential to compete with other alloys (steels, Al, etc.) for automotive applications. Nevertheless, applications of magnesium alloys remain limited due to their poor formability at room temperature. This is attributed to the strong basal texture and the limited number of active slip systems in magnesium alloys. Our current research aims to weaken the basal texture yet to enhance the strength at the same time by applying new alloy design concept. Developed alloy exhibits a relatively good tensile properties (YS: ~212 MPa, UTS: ~307 MPa and total elongation of ~17 %), but the stretch formability at room temperature is found to be significantly improved, giving the Index Erichsen (IE) value of 8 mm, which has not been achieved at such a high strength level. The role of alloying additions in microstructural evolution and mechanical properties will be discussed.
