[en] V-Nb-Ni alloys cast and annealed at subsolidus temperatures are studied using differential thermal, X-ray phase, local X-ray structure and microstructure analyses. Liquidus surface, surface of solidus and phase transformations diagram at crystallization of V-Nb-Ni system alloys are plotted on the ground of the obtained results. Presence of Laves λ₁-phase structure ternary compound (MgZn₂ type), which homogeneity range on solidus surface reaches 26-55 at.% Ni by 30 at.% Nb isoconcentrate and 20-34 at.% V by Nb₅₅Ni₄₅-V₅₇Ni₄₃ cross section is determined in the studied system

[en] Short note

[en] The composition of the Zr-(0.5-12) at. % Ru binary alloys has been studied. It has been established that the highest solubility of ruthenium in β-zirconium amounts to 11 at. % at the eutectic temperature of 1,250 deg C while the solubility in α-zirconium works out to about 1 at. % at 600 deg C. Ruthenium brings down the temperature (α reversible β) of zirconium transformation. A ω-phase, having the following lattice periods: 4.997, c=3.134 A, c/a=0.627, has been found in the alloys hardened at 1,000 and 800 deg C

[en] Vanadium solubility in liquid aluminium within 700-900 deg C temperature range is determined. The process of vanadium dissolution in liquid aluminium is shown to take place underdiffusion condition; values of vanadium diffusion coefficients in liquid aluminium are determined at 700-900 deg C

[en] Data on phase equilibria in binary and termary systems formed by molybdenum with carbon ad 4 group transition metals: titanim, zirconium, hafnium are presented. The results of investigations are given, and literature data on this problem published in Soviet and foreign press up till 1982 are systematized

[en] Ti-Ni-Zr system alloys are studied and solidus surface whithin Ti-TiNi-NiZr-Zr composition range is plotted using differential thermal, X-ray phase, local X-ray structure and microstructure analyses. Homogeneity range of Laves λ₁-phase on the basis of TiNiZr compound is determined. This phase on solidus surface is in equilibrium with all other phases of the system. Temperatures of initiation of three-phase alloy melting are determined
