氫脆（Hydrogen Embrittlement） 是材料科學中的一種失效現象，指金屬材料因吸收或滲入氫原子而導緻延展性和韌性顯著下降，在低于材料屈服強度的應力下發生脆性斷裂的現象。該過程通常不可逆，對航空航天、能源、汽車等領域的金屬構件安全性構成嚴重威脅。
氫的來源
氫原子可通過電鍍、酸洗、焊接、腐蝕反應或高溫高壓環境（如油氣管道）滲入金屬内部。例如，電鍍過程中陰極反應産生的氫原子可能被基體吸收 。
氫的擴散與聚集
氫原子在金屬晶格中擴散至應力集中區域（如裂紋尖端、晶界），形成局部高壓氫氣團或與金屬原子結合生成脆性氫化物（如钛合金中）。
脆化機制
高強度鋼、鋁合金、钛合金等對氫脆高度敏感，尤其抗拉強度 > 1000 MPa 的鋼材 。
酸性介質、海水、硫化氫環境（石油工業）及陰極保護過電位會加劇氫滲透 。
靜态或循環載荷下，應力集中區域（如螺紋、缺口）更易誘發氫緻開裂 。
選用低氫脆敏感材料（如雙相不鏽鋼），或通過微合金化（添加Ti、Nb等）固定氫原子 。
施加緻密鍍層（如化學鍍鎳）或緩蝕塗層阻斷氫滲透路徑 。

關于“hydrogen embrittlement”（氫脆）的詳細解釋如下：
氫脆是指金屬材料因吸收氫氣而導緻延展性和韌性顯著下降的現象，表現為材料在應力作用下易發生脆性斷裂。這種現象常見于鋼鐵、钛合金等金屬，尤其在氫環境（如酸性介質、高溫高壓水環境）或電化學反應中容易發生。
氫脆對航空航天、油氣管道、汽車零部件等領域的結構安全性構成威脅，需通過嚴格檢測和标準（如ISO/TR 15916）進行風險管控。
