Fracture Characteristics of Vacuum Diffusion Bonded TA2 Titanium to 1Cr18Ni9Ti Stainless Steel Joint with Nb+Ni Interlayers
Pure titanium TA2 and lCr18Ni9Ti stainless steel were vacuum diffusion bonded using Nb+Ni foils as interlayers, where Nb foil was adjacent to TA2 and Ni foil adjacent to 1Cr18Ni9Ti. The samples were heated to a temperature of 800℃ at a pressure of 10 MPa and kept for 60 rain, and then to a temperature of 900℃ at a pressure of 1 MPa and kept for 30 rain. The mechanical properties of the joint were characterized by the tensile strength test. The average tensile strength of the joints was about 398 MPa. The fracture characteristics of the joint were investigated using scanning electron microscope. The fracture of tensile test samples occurred in the Ni3Nb intermetallic compound formed in the interlayers.
