A novel, thermally resistant, dual-phase Mg alloy was prepared, and the microstructural evolution and tensile properties were investigated. The results showed that the Mg alloy matrix mainly consisted of the α-Mg and β-Li phases, and the solidified microstructure was gradually refined with increasing ZrO2 incorporation. The tensile properties of the extruded and annealed alloys were markedly improved with increasing ZrO2 content. After annealing at 603 K for 8 h, the alloy strength remained almost stable, whereas the plasticity increased. Analysis of the evolution of the properties and fracture morphology showed that this type of Mg alloy possessed good thermal resistance and formability.
