Thermal diffusivity of submicro- and nanocrystalline Zr–2.5% Nb and Zr–50% Nb alloys at high temperatures

Abstract

Measurement data are given for the thermal diffusivity of Zr–2.5% Nb and Zr–50% Nb alloys both with the usual polycrystalline structure and with submicro- and nanocrystalline structures at high temperatures, which were determined in the automated mode using the dynamic technique of plane temperature waves.
