Abstract: Superlight alloys, including Mg–8Li–1Al, Mg–8Li–1Zn and Mg–8Li–1Al–1Zn, were prepared using vacuum induction melting furnace. Microstructures and phases of the alloys were studied with optical microscope and X-ray diffraction. Mechanical properties of these alloys were measured with tensile tester. The results of tensile tests show that, the as-rolled Mg–8Li–1Al alloy with a thickness of 0.16mm has the highest tensile strength (313.9MPa). The as-extruded Mg–8Li–1Zn alloy with a thickness of 3mm has the maximum elongation (44%). The as-rolled Mg–8Li–1Al–1Zn alloy with a thickness of 0.18mm has both high tensile strength and high elongation (233.38MPa and 9.2%, respectively). [Copyright &y& Elsevier]
