电子探针在解决钢材质量、特别是对夹杂物和相成分分析方面,优于其它方法。本文介绍了用电子探针解决生产质量问题的实例。一、鉴别氧化铁夹杂或氧化锈膜的电(?)击法 1.问题的提出在生产检验中,常有一些象铁的氧化物夹杂呈“塑性”浅灰色相(图1),需电子探针鉴定。电子探针测得其主要元素为Fe、O,但铁和其它元素的X射线强度比之和,却明显低于常见的铁的氧化物夹杂。由于仪器灵敏度、相组织密度、分析物表面平整度等均可引起X射线强度比偏低,因而不能仅以铁的X射线强度比偏低来断定其不是铁的氧化物。金相观察虽可大致确认,但有其局限性,因而需采用比金相定性更准确的电子探针鉴定法。
Electron probes are superior to other methods in solving the quality of steel, especially in the analysis of inclusions and phase components. This article describes an example of using electronic probes to solve production quality problems. First, the identification of iron oxide inclusions or oxidation of the rust film of electricity (?) Attack 1. The question raised in the production test, there are often some iron oxide inclusions were “plastic” light gray phase (Figure 1), the need for electronic Probe identification. The main element of electron probe measured Fe, O, but the iron and other elements of the X-ray intensity ratio and was significantly lower than the common iron oxide inclusions. Since the sensitivity of the instrument, the density of the phase structure, the flatness of the analyte and the like can cause the X-ray intensity ratio to be relatively low, it can not be concluded that it is not an oxide of iron only because the X-ray intensity ratio of iron is too low. Metallographic observation can be generally confirmed, but its limitations, and therefore the need to use more qualitative than the qualitative identification of electronic probes.
