Experimental Investigation of the Thermal Conductivity of VT6 Alloy

The thermal conductivity coefficient of alpha- and beta-phases of the $\mathrm{Ti}$–$6\mathrm{Al}$–$4\mathrm{V}$ system is measured in the temperature range from $350$ to $1500$ K. It is shown that the alloying of titanium with admixtures of aluminum and vanadium qualitatively changes the form of the temperature dependence of thermal conductivity and the Lorentz function, which is characteristic of the basic component of the alloy, i.e., titanium. The problems of using this alloy as a standard substance in transferring a unit of thermal conductivity are discussed.
