扫描电镜在金属材料检测中的应用

Application of scanning electron microscope in metal material detection

扫描电镜是材料研究与分析中的通用设备,在材料、化工、机械等领域的微观形貌分析中起着重要的作用。本文主要从微观组织观察、材料断口分析、结合能谱仪的微区成分分析、显微织构分析四个方面简述扫描电镜的发展历程和特点以及扫描电镜及其附件在金属材料检测中的应用,为金属材料行业用扫描电镜分析提供了一定的参考依据。

SEM is a general equipment in material research and analysis,which plays an important role in the micro morphology analysis of materials,chemical industry,machinery and other fields.In this paper,the development process and characteristics of SEM and the application of SEM and its accessories in metal material detection are briefly introduced from four aspects:microstructure observation,material fracture analysis,micro zone composition analysis combined with energy dispersive spectrometer,and micro texture analysis.The application of SEM and its accessories in metal material detection provides a certain reference for the use of SEM in metal material industry.
