一、前言 材料的高温持久强度是反映材料在高温下长期工作可靠性的一个基本技术指标。然而,影响持久数据的因素很多。就持久实验室而言,试验机的机械系统、温度的控制系统、测温系统及室温的变化等等都会影响持久寿命,但到底影响如何,各说不一。为弄清上述因素对持久试验数据的影响,我们选用2只钢种对炉温波动、持久中停、试样尺寸大小做了有关试验。现将我们试验情况总结如下:
First, the preface The high temperature strength of the material is a basic technical indicator of long-term reliability of the material at high temperatures. However, there are many factors that affect long-lasting data. For a long-lasting laboratory, the test machine mechanical system, temperature control system, temperature measurement system and room temperature changes, etc. will affect the long-term life expectancy, but in the end how the impact of different. In order to understand the above factors on the impact of long-term test data, we use two kinds of steel on the furnace temperature fluctuations, long-lasting stop, the size of the sample to do the relevant tests. Now we test the situation is summarized as follows:
