![عکس صفحه اول مقاله: Effect of Sr on microstructure and aging behavior of Mg–14Li alloys Effect of Sr on microstructure and aging behavior of Mg–14Li alloys](/preview/png/1548658.png)
The as-cast and as-extruded Mg–14 wt%Li–xSr (x=0.14, 0.19, 0.39 wt%) alloys were, respectively, prepared through a simple alloying process and hot extrusion. The effects of Sr addition on microstructure and aging behavior of the Mg–14 wt%Li–xSr alloys were studied. The results indicated that β(Li) and Mg2Sr were the two primary phases in the microstructures of both as-cast and as-extruded Mg–14 wt%Li–xSr alloys. Interestingly, with the increase of Sr content from 0.14 wt% to 0.39 wt%, the grain sizes of the as-cast and as-extruded Mg–14 wt%Li–xSr alloys markedly decreased from 5000 μm and 38 μm to 330 μm and 22 μm respectively, while no obvious changes of the micro-hardness and microstructure of the as-extruded alloys were observed during the aging treatment.
