Ti2AlNb合金瞬时液相扩散连接接头界面组织及性能分析

  • 摘要: 采用Ti/Ni作为中间层实现了Ti2AlNb合金的连接(transient liquid phase, TLP),研究了TLP连接接头的界面组织及其形成机制,并且分析了不同保温时间对接头界面组织和力学性能的影响规律. 结果表明,Ti2AlNb合金TLP连接接头主要表现为等温凝固区和冷却凝固区两个明显的特征区域. 接头的典型界面组织为Ti2AlNb/B2/Nb3Al+B2+τ3+Ti2Ni/ Ti2AlNb. 随着保温时间的延长,接头中Nb3Al和Ti2Ni相消失,τ3相不断减少,B2相不断增多. 当连接温度为1 180 ℃,保温时间为20 min时,接头的室温抗剪强度最大,达到428 MPa,高温(650 ℃)抗剪强度达到407 MPa. 接头的断裂主要发生在冷却凝固区的τ3相上.
