扫描电镜在实验教学中的应用与探讨

Investigation and application of scanning electron microscopy in experimental teaching

通过金相实验教学中扫描电镜和光学显微镜对常见金相组织进行对比、鉴别、分析及实验总结,初步探索出扫描电镜在金相实验教学中的必要性和可行性.

Microstructure of common materials used in metallographic laboratory teaching, measured by SEM and optical microscope, are identified and analyzed intensively to summarize the experimental techniques and phase transformation rules. It is found that SEM is of great importance in metallographic teaching, and has excellent teaching effectiveness.
