摘要

The 450 and 600 degrees C isothermal sections of the Ni-V-Zn ternary system have been investigated through Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and x-ray Diffraction (XRD) technique. Eight three-phase regions have been confirmed at the 450 degrees C section and nine three-phase regions exist at the 600 degrees C one. Experimental results indicate that it is difficult for Ni to dissolve in VZn3 and V4Zn5. The solid solubilities of V in gamma(Ni2Zn11) and beta(1)(NiZn) are 1.4 and 3.7 at.% at 450 degrees C, respectively, while V in gamma and beta(1) are 2.5 and 4.0 at.% at 600 degrees C, respectively. The solid solubilities of Zn in Ni2V7, sigma(Ni2V3), Ni2V and Ni3V are 0.5, 4.7, 2.3 and 2.6 at.% at 450 degrees C as well as 0.5, 9.5, 2.2 and 2.8 at.% at 600 degrees C, respectively. No ternary compound has been found in this work.
