据了解,近年来不少兄弟单位和我所都先后研制了高温的布氏、洛氏、维氏和显微等硬度计,为研究和了解材料在高温下的硬度,提供了可靠的方法和设备。但对材料在低温下的硬度的研究尚缺乏科学的方法和设备。为此,我所于七一年制成了高低温真空布氏硬度计,为行业添补了空白。现把试验机的概况做如下简要的介绍。
It is understood that in recent years, many brothers and I have developed a high-temperature Brinell, Rockwell, Vickers and Microscope hardness, in order to study and understand the hardness of materials at high temperatures, provides a reliable method and equipment. However, the research on the hardness of materials at low temperature is still lack of scientific methods and equipment. For this reason, I made a high and low temperature vacuum Brinell hardness tester in July, filling a gap for the industry. Now the general situation of the testing machine to do the following brief introduction.
