氢对Al-Li合金2091-T6组织性能的影响
, PP. 1047-1052
Keywords: Al-Li合金2091－T6,氢脆,力学性能,应力腐蚀寿命,变形机制
Abstract:
本文研究了氢含量对Al－Li合金2091－T6薄板力学性能、应力腐蚀开裂寿命（SCCL）、变形机制和断口形貌的影响。结果表明，合金的氢含量由0.92μg／g降低到0.08μg／g时，力学性能和SCCL显著提高．变形机制由切割机制转变为绕过机制，拉伸和应力腐蚀试样的断裂模式由典型的沿晶脆性断裂转变为穿晶韧性断裂，氢脆引起的低韧性沿晶断裂特点完全消失.本文还讨论了脱氢对Al-Li合金变形机制和断裂模式影响的机理，提出了“超低氢Al-Li合金”的概念.
