Abstract
Mg and its alloys have drawn great interest in the materials community due to their high specific strength and potential applications in industry. In this work, we present some experimental results on two Mg-alloys, AMX602 and AZXE7 111. We have evaluated the dependence of the mechanical properties of these alloys on the extrusion temperatures under both quasi-static (strain rate ~1*10-3 s-1) and dynamic (strain rate ~4*10-3 s-1) uniaxial compressive loadings. We have observed that the quasi-static yield strength of AMX602 exhibits a slight dependence on the extrusion temperature, whereas the ultimate strength and the deformation-to-failure do not show such dependence. On the other hand, the dependence of the mechanical properties of AZXE7111 is much more complicated. We have also found that the deformation-to-failure of both alloys increases at increased strain rate. For comparison, we have tested two conventional Mg-alloys, WE43 and AZ91C under very similar conditions. We have found that AMX602 and AZXE7111 show significantly improved mechanical properties compared to WE43 and AZ91C under either quasi-static or dynamic loading. Such knowledge is particularly important for applications involving impact loading.
