“…The schematic of RFW process is illustrated in Figure 1. One component is quickly rotated and pressed against the other component, generating severe plastic deformation and a significant amount of heat at the interface [8, 9]. When enough heat has been generated, rotation is terminated and the axial pressure is maintained or increased for a period of time to promote the solid-phase bond [10, 11].…”

Pure Ni was employed as an intermediate interlayer in the dissimilar 1MnCrMoNi/X70 steels friction welding joint. The effect of the Ni interlayer on the microstructure, mechanical and corrosion properties of the joint was investigated. Compared with the Ni-free joint, the joint with the Ni interlayer had coarser microstructure and lower microhardness. Furthermore, the weld zone of the 1MnCrMoNi steel was abnormally harder than the adjacent thermo-mechanically affected zone. The tensile strength of the joint with the Ni interlayer was improved, and this joint also demonstrated a lower yield ratio, equivalent impact toughness, and enhanced corrosion resistance.
