| 摘 要： | 以超低碳钢、易切削钢、管线钢为研究对象，通过优化电解萃取法以及夹杂物自动分析技术，完成了钢中大尺寸氧化铝、大尺寸硫化锰、常规氧硫化物等典型夹杂物的三维形态表征及自动定量统计，并就滤膜干扰物、夹杂物分散状态、扫描电镜参数设置等影响夹杂物三维定量表征的因素进行了讨论。与二维分析相结合，夹杂物的三维形态表征及定量统计结果将提供最为全面、真实、准确的夹杂物信息。

| Abstract: | Three-dimensional morphological observation and statistical quantification of typical inclusions as large-size Al2O3, MnS and oxysulfides were conducted in the ultra-low carbon steel, the free cutting steel and the pipeline steel by using optimized electrolytic extraction and automated inclusion analysis technique. Some factors affecting the three-dimensional quantitative characterization of inclusions, such as the electrolytic interfering substance, the dispersion state of inclusions and the setting of SEM parameters were discussed about how to influence three-dimensional quantitative results. Combined with two-dimensional analysis, three-dimensional morphological observation and statistical quantification of the inclusions will provide more comprehensive, reliable and accurate information. |
