利用金相显微镜(OM)、场发射扫描电镜(FEG-SEM)以及基于FEG-SEM上的X射线能谱仪(EDS)和电子背散射衍射系统(EBSD)分析研究了斯太尔摩冷却的国产盘条和盐浴淬火的进口盘条的微观组织结构。组织分析结果表明,斯太尔摩盘条组织表层的晶粒平均尺寸小于心部,盘条截面不规则珠光体片层结构较多,但片间距比盐浴淬火盘条片间距细;而盐浴淬火盘条表层和心部组织差异不大,珠光体片层结构较均匀。
The effect of Stelmorom cooling on the structure of Stellite was studied by using optical microscope (OM), field emission scanning electron microscope (FEG-SEM) and X-ray fluorescence spectrometer (EDS) and electron backscatter diffraction (EBSD) Domestic wire rod and salt bath quenching the microstructure of imported wire rod. The results of microstructure analysis show that the average grain size of the surface layer of Steyr Tray is smaller than that of the heart, and the irregular pearlite lamella structure of the wire rod section is more, Bath quenching rod surface and heart tissue little difference, pearlite sheet structure is more uniform.
