Mg-6Li and Mg-6Li-1Y (wt.%) alloys were prepared using permanent model casting method, and microstructure and mechanical properties were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), optical microscopy (OM), energy dis-persive spectrometry (EDS), transmission electron microscopy (TEM), etc. The results showed that α-Mg and ?-Li phases existed in both al-loys, and there was also Y-enriched phase in Mg-6Li-1Y alloy. The composition of Y-enriched phase was near to the ma... 相似文献
