[Display omitted] • Cu-Nb composite diffused metal interlayer was first applied to TC4 and 4J36 electron beam welding. • The use of Cu-Nb interlayer produces solid solutions in the two weld melting zones. • The use of Cu-Nb interlayer improves the quality of welded joint between TC4 and 4J36. • The formation mechanism of 4J36/Cu-Nb/TC4 bonded joints was studied. Electron beam welding of 4J36 invar alloy and TC4 titanium alloy was carried out with Cu-Nb composite diffused metal interlayer. The results showed that the depth to width ratio and the tensile strength of welded joints increased with the increase of electron beam current. Under the designed process parameters, two melting zones (MZ) in welded joints formed solid solutions (ss), the welded joint tensile strength reached maximum value of 244.1 MPa, and the fracture location was mainly located at 4J36/Cu interface.
