摘要：

The 450 degrees C isothermal section of the Si-V-Zn ternary phase diagram was experimentally determined using x-ray diffraction and scanning electron microscopy coupled with energy dispersive spectroscopy. All the six three-phase regions were well determined. No ternary compound was found. Si5V6 was not detected at 450 degrees C. All the Si-V compounds can equilibrate with the liquid-Zn phase. And the V-Zn compounds, VZn3 and V4Zn5, can equilibrate with SiV3. In addition, the maximum solubilities of Zn in Si2V, Si3V5 and SiV3 were 1.0, 1.7 and 4.8 at.%, respectively, while Si had no detectable solubility in Zn-V compounds. Furthermore, thermodynamic extrapolation of the Si-V-Zn system was carried out using only the binary interaction parameters. This showed good agreement with the experimentally determined three-phase fields.
