Effect of structural characteristics and chemical composition of nanolayered interlayers based on Al–Ni system on formation of joints of g-TiAl-based alloy and high-temperature nickel alloy in vacuum diffusion welding was studied. It is shown that application of nanolayered clad interlayers ensures formation of a diffusion zone with monotonic change of the content of components, where the phase composition and micromechanical characteristics are determined by the interlayer chemical composition, as well as lowers the probability of brittle phase appearance in the butt joint. 18 Ref., 6 Tables, 7 Figures.
Keywords: vacuum diffusion welding, intermetallics, nanolayered interlayers
