Using the laser flash method and the drop method, the thermal conductivity and the enthalpy increment of the eutectic K-Pb alloy (with a Pb content of 90.7 at.%) were measured in the temperature range from the liquidus point up to 1077–1175 K. The specific heat capacity and thermal diffusivity of the alloy were calculated. Approximation equations for the studied properties were obtained, and a table of reference data was developed. It was shown that the thermal conductivity of the liquid eutectic is less than that of pure lead and increases with temperature.

液态共晶K-Pb合金的热物理性质

使用激光闪光法和滴落法，在从液相线到最高1077–1175的温度范围内测量了共晶K-Pb合金（Pb含量为90.7 at。％）的热导率和焓增量。 K.计算合金的比热容和热扩散率。获得了所研究性质的近似方程，并开发了参考数据表。结果表明，液体共晶的导热系数小于纯铅的导热系数，并且随着温度的升高而升高。
