Abstract

The thermal conductivity and thermal diffusivity of europium (Eu) in the solid and liquid states, including the melting-crystallization region, have been measured for the first time by the laser flash method in the temperature range from 298 to 1625 K. The error of measurement of the heat transfer coefficients was 4–6%. The data for the temperature regions of 298–550 K and 965–1625 K were obtained for the first time. Fitting equations and reference data for the temperature dependence of the thermal conductivity and thermal diffusivity of the metal have been received.

在298–1625 K温度范围内的导热率和热扩散率

摘要

the（Eu）在固态和液态（包括熔融结晶区域）的导热率和热扩散率是首次通过激光闪光法在298至1625 K的温度范围内测量的。传热系数的测量值为4–6％。首次获得了298–550 K和965–1625 K温度区域的数据。已经收到了金属的热导率和热扩散率与温度的关系的拟合方程和参考数据。
