金屬試樣(metallographic specimen)是材料科學與工程領域中用于微觀結構分析的标準化樣品,通常指經過特定制備工藝處理的金屬或合金材料。其核心作用在于通過顯微組織觀察揭示材料内部晶體結構、相組成及缺陷特征。
組成與制備要求
金屬試樣需滿足ASTM E3标準規定的制備規範,包括切割、鑲嵌、研磨、抛光和化學蝕刻五個關鍵步驟。其中電解抛光技術可有效消除機械損傷層,提升顯微組織清晰度(來源:《材料表征技術原理》)。
分析技術體系
工業應用場景
在航空發動機葉片失效分析中,金屬試樣的析出相分布檢測可準确判定熱處理工藝缺陷。汽車闆件腐蝕研究中,試樣界面結構分析能追溯電鍍工藝異常(來源:NIST材料數據庫)。
metallographic specimen 是由“metallographic”(金相的)和“specimen”(樣本)組成的術語,具體解釋如下:
Metallographic(金相的)
形容詞,源自名詞“metallography”(金相學),指通過顯微鏡研究金屬或合金微觀結構的學科。例如,定量金相法(quantitative metallography)可用于分析鋼中鐵素體的應變。
Specimen(樣本)
名詞,指用于檢驗、觀察或實驗的樣品或标本。在工程領域,常指經過特定處理的材料樣本,如岩石标本、金屬試樣等。
metallographic specimen 指用于金相分析的金屬或合金樣本,需經過研磨、抛光等制備步驟,以便在顯微鏡下觀察其顯微組織(如晶粒、相分布等)。
該術語專指經過制備、用于金相學研究的金屬樣本,是材料科學與工程中評估材料性能的關鍵對象。
