| Abstract: | Vacuum diffusion bonding between titanium alloy TC4 and austenitic stainless steel 1Cr18Ni9Ti was carried out by using conventional and ladder-like processing methods with Ni+Nb as interlayers.The microstructure and elements distribution of the joints were analyzed by OM,SEM and EDS.The mechanical properties of the joints were characterized by tensile strength test.Meanwhile the fracture surfaces were analyzed too.The results showed that Ni+Nb interlayers successfully prevent the formation of Fe-Ti intermet... |
