金屬顯微鏡（Metallographic Microscope）是一種專門用于觀察金屬材料微觀組織的精密光學儀器。它通過光學放大系統揭示金屬及合金的晶粒結構、相組成、夾雜物分布、缺陷特征等關鍵信息，是材料科學、冶金工程和工業質量控制的核心分析工具。
反射光照明系統
區别于生物顯微鏡的透射光，金屬顯微鏡采用垂直入射的反射照明光源（如LED或鹵素燈），光線經物鏡照射到抛光後的金屬樣品表面，反射光攜帶微觀形貌信息進入物鏡成像。這種設計解決了金屬等不透明材料的顯微觀察難題。
高分辨率物鏡與對比度增強技術
配備長工作距離、高數值孔徑（NA）的平場消色差物鏡（如50×、100×油浸物鏡），結合微分幹涉相襯（DIC）或暗場照明技術，可清晰分辨亞微米級晶界、析出相及微裂紋。例如，DIC技術通過偏振光幹涉增強表面高度差對比度，使晶界三維形貌可視化。
金屬顯微鏡分析高度依賴标準化的樣品制備流程：
材料研發
分析合金凝固組織（如鋁合金枝晶臂間距）、相變産物（鋼中馬氏體/貝氏體比例），指導成分設計與熱處理工藝優化。
工業失效分析
識别疲勞斷口的輝紋、應力腐蝕裂紋路徑（如核電管道晶間開裂），追溯機械部件斷裂根源（參考：Practical Metallography期刊案例）。
質量控制
量化晶粒度（ASTM E112标準）、夾雜物評級（ASTM E45），确保航空航天緊固件、汽車齒輪等關鍵部件性能達标。
金相檢驗标準體系 涵蓋樣品制備、顯微組織評級等規範。

"Metallographic microscope"（金相顯微鏡）是材料科學領域的重要儀器，其含義和應用可分解如下：
1. 詞源與構成
2. 核心功能 用于觀察金屬材料經抛光、腐蝕等處理後呈現的顯微組織，包括晶粒結構、相組成、缺陷分布等特征。通過連接攝像裝置可進行圖像數字化分析與存儲。
3. 主要應用領域
4. 技術特點 相比普通光學顯微鏡，其具備更強的反射照明系統、特殊物鏡設計（如長工作距物鏡）以及偏光觀察功能，可適應金屬樣品的高反射特性。
相關術語補充
在定量分析中常使用 quantitative metallography（定量金相學）方法，該技術依賴于金相顯微鏡獲取的顯微圖像進行數值化測量分析。同類型設備有時也被稱為 metallurgical microscope（冶金顯微鏡）。
