Abstract

Melting and solidification temperatures for Ni-Mo alloys (the ratio of these elements is 3:1) containing 10% (by weight) of vanadium carbide are determined. Introduction of vanadium carbide into Ni-Mo alloy reduces the melting temperature by 20°C. The alloys consist of two phases: a solid solution based on nickel and a carbide component resembling needle-shaped inclusions of the eutectic type. Traces of eutectic are observed with 1% VC in a sample. Dissolution of vanadium in the Ni-Mo alloy mentioned does not exceed 1% (by weight). The presence of two phases and their approximate composition in the alloys are confirmed by x-ray diffraction analysis. The solid solution based on nickel contains molybdenum (10–20%) and vanadium (1–6%). The carbide component is a vanadium-containing phase based on molybdenum with a crystal lattice of the Mo2C type.
