摘要

摘要描述了使用相对方法测量线膨胀系数（CLE）的高温（高达 1600°C）装置。该测量装置安装在一个保护性手套箱中，可以对在反应器中经过辐照的样品进行测量。样品在加热过程中的长度变化由时钟型指示头记录，精度为 1 μm，测量范围为 0-10 mm。该装置用于确定高温退火过程中辐照样品的膨胀值，并获得有前途的反应器材料的 CLE 值。平均相对测量误差为 8-11%。

A High-Temperature Installation for Measuring the Coefficient of Linear Expansion

Abstract—

A high-temperature (up to 1600°C) installation for measuring the coefficient of linear expansion (CLE) using a relative method is described. The measuring unit is installed in a protective glove box, which allowed measurements to be performed on samples irradiated in a reactor. Changes in the length of the sample during heating were recorded with a clock-type indicator head with an accuracy of 1 μm with the measurement range of 0–10 mm. The installation was used to determine the values of swelling of irradiated samples during high-temperature annealing and to obtain the values of the CLE of promising reactor materials. The average relative measurement error is 8–11%.
