金相分析(Metallographic Analysis)是材料科學中用于研究金屬或合金微觀結構的關鍵技術,通過觀察材料内部晶粒、相組成、缺陷分布等特征,評估其物理性能和加工曆史。該技術廣泛應用于航空航天、汽車制造、機械工程等領域,為材料質量控制、失效分析及工藝優化提供依據。
核心步驟包括:
典型應用中,金相分析可揭示熱處理效果(如淬火後馬氏體形态)、焊接缺陷(如氣孔、裂紋)以及疲勞斷裂機制。例如,航空發動機葉片通過該技術檢測高溫合金的蠕變孔洞,以預測使用壽命(來源:Springer Materials數據庫)。
權威機構如美國材料與試驗協會(ASTM)制定了相關标準(如ASTM E407-07),規範了不同金屬的制樣與腐蝕流程,确保分析結果的可重複性。
Metallographic analysis(金相分析)是通過對金屬材料的微觀組織結構進行觀察和研究,以評估其性能、工藝質量及材料缺陷的分析方法。以下是綜合多個來源的詳細解釋:
