1.淬透性测试误差研究 提出了研究淬透性测试误差的方案。此方案是新的,有广泛的适用性。按此方案所得具体结果只是一个例证。通过试验得到了硬度计引入的恒差和变差,夹具的变差及其在总变差(包括硬度计和夹具分别引入的变差)中所占的比重,使用夹具情况下硬度测定值的校正值等。还提出了测定晶粒度应注意的问题以及关于确定钢的半马氏体距离的建议。
1. Hardenability test error study proposed a study of the hardenability test error scheme. This program is new and has wide applicability. The specific result of this program is just an example. The constant and variation introduced by the hardness tester, the variation of the fixture and its proportion in the total variation (including the variation introduced by the hardness tester and the fixture, respectively) were obtained by the test, and the hardness Correction value and so on. It is also proposed that attention be given to the determination of grain size and to the suggestion of determining the half-martensite distance of the steel.
