发布时间：2023-10-06 15:26

　　The modification effects of ytterbium(Yb), Na₃PO₄ and Yb + Na₃PO₄ on primary Mg₂Si phase in Mg-4Si alloys were investigated by means of X-ray diffraction(XRD), optical microscopy(OM), scanning electron microscopy(SEM) and energy dispersive spectroscopy(EDS) analysis in this work. The results indicate that the morphology of the primary Mg₂Si phase apparently changes from coarse dendrites to fine dispersive polygonal particles and t...
