钢中非金属夹杂物是对钢材组织和性能危害最大的缺陷之一,为了生产出高品质的钢材,对钢中夹杂物的检测是极为重要的.本文首先简要概述了近年来出现的夹杂物检测新方法,然后筛选出几项前沿技术进行了深入探讨,分别是ASPEX扫描电镜自动分析技术、显微计算机断层扫描技术(Micro-CT)、连续切片扫描电子显微分析技术(SBFSEM)、透射电镜分析技术(TEM)、聚焦离子束结合三维原子探针层析技术(FIB-3DAP-APT)、激光诱导击穿光谱法(LIBS)、大尺寸样品火花映射原位分析法(OPA-SMALS)、悬浮炼钢观测夹杂物法,对这几项技术的最新应用进展进行了分析,并通过相互对比概括出各自的优缺点.同时介绍了采用扫描电镜检测夹杂物成分时电子束能量的选择对检测结果的影响,最后指出了各项检测技术在未来需要进一步改进和发展的方向.
Progress in detection technologies of non-metallic inclusions in steel
The non-metallic inclusion in steel is one of defects that have the greatest hazard to steel struc-tures and properties.The detection of inclusions in steel is critical to the production of high-quality steels.In this paper,the new detection methods for inclusions developed in recent years were briefly summarized.Then several advanced technologies were screened for the deep discussion,including ASPEX scanning elec-tron microscope automatic analysis,micro-computed tomography(Micro-CT),continuous slice scanning e-lectron micropy analysis(SBFSEM),transmission electron microscope(TEM)analysis,focused ion beam three-dimensional atom probe-atom probe tomography(FIB-3DAP-APT),laser-induced breakdown spec-troscopy(LIBS),original position statistical distribution-spark mapping analysis for large samples(OPA-SMALS),and suspension steelmaking inclusion observation.The latest application progress of these tech-nologies was analyzed,and the advantages and disadvantages were summarized via mutual comparison.Mo-reover,the influence of electron beam energy selection on the detection results during the inclusion compo-sition analysis by scanning electron microscope was also introduced.Finally,the direction for further im-provement and development of various detection technologies in future was pointed out.
