The vacuum brazing tests of Cu and Mo were realized by using AgCuTi active filler metal,and good brazed joint was obtained.The interfacial structure and element distribution of brazed joints were analyzed by means of SEM,EDS and other testing methods,and the bonding mechanism of the joint was discussed.The results show that the typical interfacial microstructure of Mo/AgCuTi/Cu joints are Mo+Mo Ti solid solution + eutectic structure +Cu based solid solution + rich Ag zone+Cu.In the welding process,the Ti at...
