It is established that VDW using NF system Ni-Cu/Ti-Ni-Hf allows to obtain defect-free joints with almost homogeneous distribution of chemical elements. The efficiency of using Ti(Nb)/Al and Nb/Ti-Ni/Nb foils in RBW of TiAlNb alloy is studied. A significant effect of the use of NF Ti(Nb)/Al in the processes of resistance heating of the joint area has been established. The formation of defect-free joints using NF is ensured by the reaction diffusion of the components of NF and TiAlNb alloy, the localization of the processes of heat release and plastic deformation of contact volumes of metal.
