ABSTRACT:
A dual-phase magnesium-based alloy consisting essentially of about 7-12% lithium, about 2-6% aluminum, about 0.1-2% rare earth metal, preferably scandium, up to about 2% zinc and up to about 1% manganese. The alloy exhibits improved combinations of strength, formability and/or corrosion resistance. There is also disclosed a composite matrix whose metal phase consists essentially of the aforementioned composition.
