摘　　要：用BNi2,Fe78Si9B13和FeNiCrSiB合金箔作中间层,氩气保护,分别对TP304和T91钢管进行了瞬时液相扩散(TLP)连接。分析了TLP连接接头的显微组织、力学性能和元素分布;确定出了合适的连接工艺参数。研究表明,TP304用BNi2和FeNiCrSiB作中间层,T91用FeNiCrSiB作中间层连接的接头室温下的抗拉强度和抗弯强度等于或超过基体。TP304 and T91 steel pipes were joined by transient liquid-phase bonding process using BNi2, Fe^SigBI3 and FeNiCrSiB filler in argon atmosphere. The mierostructures, properties, as well as the element distribution of the joints have been examined, and TLP bonding parameter is determined. The test results showed that the tensile strength and bencl strength at room temperature of the joint of TP304 with BNi2 and FeNiCrSiB filler was equal to or greater than that of the base metal, and so was Tgl with FeNiCrSiB filler.
