Thermophysical Properties of Zirconium Alloy E110 (Zr-0.01Nb) after Oxidation in Air Atmosphere

The subsecond resistive pulse heating technique has been used to study the temperature dependence of the heat capacity and spectral emissivity (for the wavelength of 0.65 mm) of the zirconium alloy E110 (Zr-0.01Nb) after oxidation in air atmosphere. The tubular samples were oxidized at multiple pulse heating cycles up to different maximum temperatures (1200, 1300, 1400, 1500, and 1600 K) and subsequent cooling. It is shown that the thermophysical properties of the oxidized samples depend on the maximum temperature of oxidation.
