| 摘 要： | 提出了对金属材料在无负载条件下进行尺寸稳定性评定的热循环在线检测法。实验证明：这种方法能对试样在热循环过程中的尺寸变化进行实时检测，可同时获得材料在每次热循环之后的尺寸变化规律和多次循环之后的尺寸变化总量，用它来评价不同材料或同一材料经不同工艺处理之后的尺寸稳定性非常直观和方便，具有测试周期短、精度高的特点。

| Abstract: | Thermal cycling on-line measuring method was proposed to evaluate the dimensional stability of metal materials unloaded. The test results show that during thermal cycling, not only the dimension change of the samples can be measured at all time, but also the dimension change after every cycling and the sum of change after multiple cycling can be measured. So it is very convenient and visual to evaluate the dimensional stability of different materials or the same material treated by different procedures. |
