Simultaneous measurements of specific heat, electrical resistivity, and hemispherical total emittance of niobium-1 (wt. %) zirconium alloy in the temperature range 1500 to 2700 K by a subsecond duration pulse heating technique are described. Estimated inaccuracy of measured properties are: 3 percent for specific heat and hemispherical total emittance, and 0.5 percent for electrical resistivity. Properties of the alloy are compared with the properties of pure niobium. It was found that specific heat and emittance of the alloy were approximately 0.5 percent and 1.5 percent, respectively, higher than those of pure niobium. Electrical resistivity of the alloy was 0.5 percent lower than that of pure niobium. Like niobium, the alloy showed a negative departure from linearity in the curve of electrical resistivity versus temperature.
描述了采用持续时间为亚秒级的脉冲加热技术，在1500至2700K温度范围内同时测量铌 - 1（重量百分比）锆合金的比热、电阻率和半球总发射率。所测性能的估计误差为：比热和半球总发射率为3%，电阻率为0.5%。将该合金的性能与纯铌的性能进行了比较。结果发现，该合金的比热和发射率分别比纯铌高约0.5%和1.5%。该合金的电阻率比纯铌低0.5%。与铌一样，该合金在电阻率与温度的曲线上也呈现出负的线性偏差。
