It is shown that the presence of an interlayer between the surfaces being joined leads to formation of a strong (about 70 % of strength of the base metal) welded joint with no change in uniformity of distribution of the reinforcing particles (Al2O3). An activating effect of the interlayer on the process of diffusion welding is provided by the reaction of synthesis to form the NiAl3 intermetallic phase within the joint zone, the phase being fragmented and dissolved in the composite matrix phase under the conditions of heating under pressure
Keywords: diffusion welding, composite, electron beam deposition, nanolayered foil, solid-phase synthesis
