|metallographic test;[材]金相檢驗
metallographic examination（金相檢驗） 是指通過制備金屬樣品、利用光學或電子顯微鏡觀察其顯微組織結構的材料分析方法。其核心目的是揭示材料的晶粒尺寸、相組成、夾雜物分布、缺陷形态等微觀特征，從而評估材料的加工工藝質量、力學性能及失效原因。
切割、鑲嵌、研磨、抛光金屬試樣，消除表面劃痕，必要時通過化學或電解腐蝕凸顯組織邊界。此過程需避免引入假象，确保觀察結果真實反映材料内部狀态。
使用光學顯微鏡（放大率50–1000倍）或掃描電子顯微鏡（SEM）觀察顯微組織。例如，可識别鋼中珠光體、鐵素體的比例，或鋁合金中析出相的分布。
結合圖像分析軟件測量晶粒度（如ASTM E112标準）、第二相體積分數等參數，為材料性能提供數據支撐。
通過關聯微觀組織與宏觀性能（如強度、韌性），金相檢驗為材料設計、工藝優化及産品失效診斷提供科學依據，是材料科學與工程領域的基石分析方法之一。
metallographic examination（金相檢驗）是材料科學中用于分析金屬材料微觀結構的重要技術手段，具體解釋如下：
定義與核心作用
指通過金相顯微鏡、電子顯微鏡等工具觀察金屬或合金的顯微組織，評估材料的晶粒尺寸、相組成、缺陷分布等微觀特征。其目的是判斷材料性能是否符合要求，常用于失效分析或質量控制。
應用領域
廣泛應用于機械制造、冶金、航空航天等領域，例如：
檢驗内容
主要包括：
相關技術關聯
常與化學分析、硬度測試、超聲探傷等技術聯合使用，形成完整的材料性能評估體系。例如提到通過金相分析結合硬度測試判斷鋼軌斷裂原因。
擴展說明：該術語中的"metallographic"源自金屬學（metallography），強調對材料微觀結構的系統性研究。如需更專業的檢測流程，可參考材料科學标準如ASTM E3等。
