“…Dynamic vacuum of 10 -3 Pa was maintained in the working chamber during measurements. The details of the structure of the working section and of the procedure of processing the measurement results in view of all necessary corrections were described in [2,3]. The limiting error of measurements of the thermal conductivity coefficient is in the range of 5-7%.…”

Experimental data are obtained for the thermal conductivity coefficient of zirconium containing 2.5% niobium. The investigated temperature range of 400 to 1600 K covers the range of existence of hexagonal (alpha-phase) and cubic (beta-phase) structural modifications of the alloy. The low-temperature and high-temperature structures differ by the value of the temperature derivative of the thermal conductivity coefficient. The thermal cycling of sample under vacuum of 10 -3 Pa leads to a gradual decrease in thermal conductivity, which is especially pronounced at low temperatures. The available data on electrical resistance for the alpha-phase region are used to estimate the Lorentz function. The obtained values of Lorentz number are indicative of the predominating part played by the electron mechanism of thermal conductivity in the alloy. The values of thermal conductivity measured for the beta-phase are used to determine the electrical conductivity of the alloy.

“…The basic array of data on thermal conductivity of hafnium was obtained in [27,28] using the method of longitudinal heat flux. The method of radial temperature waves, which enables one to simultaneously measure the heat capacity, thermal conductivity and diffusivity of one and the same sample, was used by Arutyunov et al [8] for obtaining data on thermal conductivity of hafnium.…”

New experimental data are given for the KhN55VMTKYu industrial nickel-based heat-resistant alloy on its heat capacity at temperatures from 300 to 1000 K and on the thermal conductivity coefficient at T = 380-1450 K. The newly obtained and previously available data are used to construct approximating equations and tables of smoothed values in the range from 300 to 1200 K for heat capacity, enthalpy, average heat capacity, thermal conductivity, average coefficient of thermal expansion, density, and thermal diffusivity of the alloy. The effect of disordering of the Ni 3 (Ti, Al) intermetallic compound on the properties of the alloy is examined. The activation energy of disordering of the alloy Q = 0.93 eV and the temperature dependence of the enthalpy of disordering are estimated, as well as the concentration of intermetallic compound in the alloy.
