|intercrystalline corrosion/intergranular attack;[材]晶间腐蚀；粒间腐蚀
晶间腐蚀（Intergranular Corrosion）是金属材料在特定环境下发生的一种局部腐蚀形式，其特点是腐蚀优先沿着金属晶粒边界扩展，导致材料强度显著下降。该现象常见于不锈钢、铝合金等合金中，由晶界区域的化学成分差异或微观结构变化引起。
从腐蚀机理分析，晶间腐蚀的核心成因是晶界处发生选择性贫化或析出相。例如，奥氏体不锈钢在450-850℃敏化温度范围内，碳与铬结合形成碳化铬（Cr₂₃C₆）沿晶界析出，导致邻近区域铬含量低于钝化所需的12%临界值，形成电化学活性差异。这种贫铬区域在酸性或含氯介质中成为阳极，加速晶界溶解。
典型应用案例包括：
预防措施主要基于材料工程控制：
检测方法依据ASTM A262标准，通过草酸浸蚀试验或Streicher测试评估材料敏化程度。美国腐蚀工程师协会（NACE）SP0170标准则规定了油气环境中材料抗晶间腐蚀的验收标准。
intergranular corrosion（晶间腐蚀）是一种局部腐蚀现象，指沿着金属晶粒间的边界向内部扩展的腐蚀形式，常见于不锈钢、铝合金、黄铜等材料中。以下是详细解释：
基本概念
晶间腐蚀是由于晶界区域与晶粒内部的化学成分或物理状态差异引起的。例如，晶界处可能富集杂质、合金元素偏析或存在内应力，导致该区域优先被腐蚀。
表现形式
腐蚀后金属表面可能仍保持光泽，但晶粒间的结合力显著减弱，导致材料力学性能（如强度、韧性）急剧下降，甚至无法承受敲击。
如需进一步了解具体材料的标准或检测方法，可参考相关行业规范（如ASTM A262）。
