High-temperature thermal conductivity of zirconium-based alloys
Vladislav E Peletsky
The thermal conductivity of zirconium-based alloys has been measured at temperatures between 400 and 1700 K by a steady-state longitudinal heat-flow technique. A sharp increase of the conductivity temperature coefficient was found at the change of crystal structure of the alloys studied. The temperature dependence of the Lorenz function has been determined to evaluate the electronic and lattice contributions to the thermal conductivity of both alpha and beta solid phases of the metals studied.
