|intercrystalline corrosion/intergranular attack;[材]晶間腐蝕；粒間腐蝕
晶間腐蝕（Intergranular Corrosion）是金屬材料在特定環境下發生的一種局部腐蝕形式，其特點是腐蝕優先沿着金屬晶粒邊界擴展，導緻材料強度顯著下降。該現象常見于不鏽鋼、鋁合金等合金中，由晶界區域的化學成分差異或微觀結構變化引起。
從腐蝕機理分析，晶間腐蝕的核心成因是晶界處發生選擇性貧化或析出相。例如，奧氏體不鏽鋼在450-850℃敏化溫度範圍内，碳與鉻結合形成碳化鉻（Cr₂₃C₆）沿晶界析出，導緻鄰近區域鉻含量低于鈍化所需的12%臨界值，形成電化學活性差異。這種貧鉻區域在酸性或含氯介質中成為陽極，加速晶界溶解。
典型應用案例包括：
預防措施主要基于材料工程控制：
檢測方法依據ASTM A262标準，通過草酸浸蝕試驗或Streicher測試評估材料敏化程度。美國腐蝕工程師協會（NACE）SP0170标準則規定了油氣環境中材料抗晶間腐蝕的驗收标準。
intergranular corrosion（晶間腐蝕）是一種局部腐蝕現象，指沿着金屬晶粒間的邊界向内部擴展的腐蝕形式，常見于不鏽鋼、鋁合金、黃銅等材料中。以下是詳細解釋：
基本概念
晶間腐蝕是由于晶界區域與晶粒内部的化學成分或物理狀态差異引起的。例如，晶界處可能富集雜質、合金元素偏析或存在内應力，導緻該區域優先被腐蝕。
表現形式
腐蝕後金屬表面可能仍保持光澤，但晶粒間的結合力顯著減弱，導緻材料力學性能（如強度、韌性）急劇下降，甚至無法承受敲擊。
如需進一步了解具體材料的标準或檢測方法，可參考相關行業規範（如ASTM A262）。
