Conclusions A constitution diagram of the VC0.88-VB2 system has been constructed on the basis of data yielded by metallographic examinations, x-ray diffraction and chemical analyses, melting point determinations on alloys, and microhardness measurements on their individual phases. The diagram is of the eutectic type, with Teut = 2120 ± 20°C, the composition of the eutectic being 54 mole % VC + 46 mole % VB2. Vanadium carbide dissolves up to 10 wt. % of VB2 at Teut, the solubility of VC in VB2 being negligible.Translated from Poroshkovaya Metallurgiya, No. 2(230), pp. 49–51, February, 1982. 相似文献
