Abstract Scope |
Three dual-phase Mg-6Li-2Gd, Mg-7Li-2Gd and Mg-8Li-2Gd (wt.%) alloys, with different morphology of β-Li and α-Mg phases, were fabricated by hot extrusion and then in-situ tension tested at room temperature (RT). Digital image correlation (DIC) technique and slip trace analysis were utilized to investigate the effect of phase morphology, including the size and configuration of β-Li and α-Mg phases, on the microscopic deformation behavior of Mg-Li-Gd dual-phase alloys. The small α-Mg phase enclosed in a three-dimensional continuously connected network of β-Li phase in Mg-8Li-2Gd (wt.%) alloys was observed to be distributed homogeneously by fine slip traces and triggered a large amount of deformation. The different microscopic deformation behaviors were thus discussed. |
