摘要

The isothermal section of the Y-Co-V system at 500 °Chas been investigated by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy. Only one ternary compound YV_xCo_(12-x) with a homogeneity range of 1.30<=x<=3.64 was found in this system. The maximum solid solubilities of V in Y_2Co_(17), Y_2Co_7, YCO_3, YCo_2 and Y3C0 are about 10.0,1.0, 3.0,4.0 and 4.0at.% V, respectively. The compounds VCo and VCo_3 have a homogeneity range of 46-66 at.% V and 22-30 at.% V, respectively. The maximum solid solubility of Y in VCo is about 2.0 at.% Y.
