THE PHASE DIAGRAM OF THE NIOBIUM-MOLYBDENUM-VANADIUM SYSTEM AND CERTAIN PROPERTIES OF ITS ALLOYS (in Russian)
Previous studies of the binary systems Nb--Mo, Nb--V, and Mo--V revealed unlimited mutual solubility of the components in both solid and liquid phases, pointing to the probability of such an unlimited solubility in the ternary system Nb--Mo--V. The phase diagram of the ternary system was determined by measuring the melting points of the various alloy compositions in the system and by studying their microstructure. The existence of unlimited solid solubility was verified. While establishing the solidus curve, it was found that the melting point is lowered from 2450to 1800 deg C as the vanadium content is increased. The niobium corner of the triangular diagram presented the lowest hardness in the system, ranging from 105 to 220 kg/mm/sup 2/. The highest heat resistance was shown by alloys with high niobium content; those containing large amounts of molybdenum and vanadium were easily oxidized. The hardness measurements confirmed the existence of a continuous series of solid solutions in the system. (TTT)
