摘要
Titanium alloy TC1 and Aluminum alloy LF6 were butt jointed by friction stir welding (FSW) using zinc as the middle layer material. Influence of zinc on the microstructure and brittle phases were studied. The results show that, the microstructure of the nuclear zone is a mixture structure with Ti alloy particles distributed on Al alloy substrate. At the same time, XRD test results show that there TiAl3 intermetallic compounds and Zn0.69Ti0.31 intermetallic compounds in the nuclear region. The joint which is added zinc as the middle layer material becomes more brittle.
