- Abstract
We report on the thermal diffusivities, specific heats, thermal conductivities, and electrical resistivities of 21 alloys of the nickel–vanadium system. It is found that heat transfer in NiV alloys is mainly executed by electrons. The behavior of temperature dependences of these properties shows that in the temperature range under investigation, the thermophysical characteristics of samples in the state of solid solutions and intermetallic compounds differ significantly because of the dependence of the energy structure of collectivized electrons on the system composition and temperature. It is shown that the concentration range in which the mutual solubility of component is ensured expands upon heating. The Nordheim rule for the alloys under investigation holds at temperatures close to the melting point and indicates the dependence of the density of states of collectivized electrons on the concentration of components.
