Paper Abstract

Light-weight metal or alloy was widespread in aerospace and aeronautical engineering. Alloy Li-Mg was the lightest metal structural materials. Focus was recently on this alloy. Static mechanical properties were important for materials before they were applied into practical use. Static Testing of a new alloy Li-Mg was accomplished in this paper by universal materials testing system Model INSTRON 5500R. Stress-strain curve was acquired. And ultimate stress, yield stress, elongation in percentage and reduce of area in percentage were measured in detail. The result showed that alloy had higher strength to 250MPa in tension. But the deformation was hardly changed in length or section before it cracked. All the experimental result proved that this material was typical brittle materials. Fractography had been observed by scanning electron microscope (SEM). SEM Photos were also verified alloy Li-Mg was ductile material.
