扫描电镜及能谱仪在粉末冶金高速钢夹杂物分析中的应用

Applications of SEM with EDS in Analysis of Nonmetallic Conclusions in Power Metallurgy High Speed Steel

介绍了扫描电镜和能谱仪在粉末冶金高速钢中夹杂物分析中的应用。通过扫描电镜和能谱仪，不仅能观察到金相试样和弯曲断1：7试样中的夹杂物形貌、尺寸，还能同时分析其成分，对研究夹杂物对粉末高速钢性能的影响有重要指导意义。

Applications of scanning electron microscope （SEM） with energy dispersive microanalysis （El）S） in analysis of nonmetallic conclusions in powder metallurgy high speed steels （PM HSS） are introduced in this paper. Micro--textures of nonmetallic conclusions in metallographic specimen and bending fractures can be observed, at the same time, point element a- nalysis can be obtained by using SEM with El）S, which can have instructive use in investigating the effects of nonmetallic con- clusions on the properties of PM HSS.
