摘要：
The 450 and 600 A degrees C isothermal sections of the Zn-Cr-Si system were experimentally constructed using scanning electron microscopy equipped with energy dispersive x-ray spectrometry, and x-ray diffraction. Six three-phase regions in the 450 A degrees C section and five three-phase regions in the 600 A degrees C section were identified experimentally. No ternary compound was found. Si has low solubility in CrZn17. The Zn solubility in CrSi2, Cr5Si3, and Cr3Si are all less than 2.2 at.%. The CrSi phase cannot be in equilibrium with the eta-Zn phase. Thermodynamic extrapolation of the Zn-Cr-Si system was carried out and showed good agreement with experimentally determined phase relationships.
