Microstructure and Intrinsic Coercive Force of Sm2Co17 Type Permanent Magnet Alloys by Aging Treatment

摘要:

采用扫描电子显微镜(SEM)结合X射线能谱仪(EDS)对Sm2Co17型钐钴永磁合金时效处理过程中的显微结构与成分的变化进行分析，揭示该类永磁合金的显微结构在时效过程中随着时效温度和时间的改变而变化的规律，明确正常样品的典型显微结构SEM照片。此方法较光学显微镜的显微结构结果更加准确直观，较透射电子显微镜则有制样简单和分析快速的特点，在产品质量控制中应用效果显著

Abstract:

Scanning electron microscopy (SEM) and energy dispersive X-ray spectrometer (EDS) were used to analyze the microstructure and composition changes in the aging process of Sm2Co17 type permanent magnet. The microstructure changes of such magnets in the aging process with the aging temperature and time changes in the law were revealed, and the typical SEM image of microstructure of normal sample was identified. The result of this method is more accurate and more intuitive than optical microscope, and the sample preparation is easier than that of transmission electron microscopy. The application in the production control effect is remarkable
