金属显微镜（Metallographic Microscope）是一种专门用于观察金属材料微观组织的精密光学仪器。它通过光学放大系统揭示金属及合金的晶粒结构、相组成、夹杂物分布、缺陷特征等关键信息，是材料科学、冶金工程和工业质量控制的核心分析工具。
反射光照明系统
区别于生物显微镜的透射光，金属显微镜采用垂直入射的反射照明光源（如LED或卤素灯），光线经物镜照射到抛光后的金属样品表面，反射光携带微观形貌信息进入物镜成像。这种设计解决了金属等不透明材料的显微观察难题。
高分辨率物镜与对比度增强技术
配备长工作距离、高数值孔径（NA）的平场消色差物镜（如50×、100×油浸物镜），结合微分干涉相衬（DIC）或暗场照明技术，可清晰分辨亚微米级晶界、析出相及微裂纹。例如，DIC技术通过偏振光干涉增强表面高度差对比度，使晶界三维形貌可视化。
金属显微镜分析高度依赖标准化的样品制备流程：
材料研发
分析合金凝固组织（如铝合金枝晶臂间距）、相变产物（钢中马氏体/贝氏体比例），指导成分设计与热处理工艺优化。
工业失效分析
识别疲劳断口的辉纹、应力腐蚀裂纹路径（如核电管道晶间开裂），追溯机械部件断裂根源（参考：Practical Metallography期刊案例）。
质量控制
量化晶粒度（ASTM E112标准）、夹杂物评级（ASTM E45），确保航空航天紧固件、汽车齿轮等关键部件性能达标。
金相检验标准体系 涵盖样品制备、显微组织评级等规范。
