摘　　要：在开放环境下,使用氩气保护,对珠光体耐热钢12Cr1MoV和6063铝合金异种金属的瞬时液相扩散工艺与组织进行了研究。采用Ai-Si箔中间层,压力5 MPa。研究表明,瞬时液相扩散工艺可以实现钢/铝异种金属的焊接,在600℃等温10 min获得了结合良好的接头。分析表明,界面结合良好,没有钎焊时容易出现的金属间化合物。The dissimilar metal steel and aluminum were welded by transient liquid-phase bonding(TUP) using Al-Si filler in argon atmosphere at the bonding pressure of 5 MPa.The elements diffusion process and the microstructures of the transient liquid- phase bonded joint were analyzed by changing holding time and bonding temperature.The test results showed that the steel and aluminum alloy are successfully joined by TUP bonding process.The microstructures and properties of TUP bonded joint are best at the bonding temperature of 600 ℃ and holding time of 10 min.The bonded interfaces combines well and have no intermetallic compounds.
