Abstract The impact of lanthanum addition on the microstructural changes and mechanical characteristics of Mg–9Li–3Al + xLa alloys are studied. The alloys are fabricated through a liquid metallurgy route involving stir casting by an electrical resistance furnace. The microstructural analysis showed that the as-cast alloys primarily comprises of α-Mg and β-Li phases. Irregular distribution of Al–Li lamellar and some granular fragments MgLi 2 Al observed over the magnesium-rich α-phase and… Expand
