Abstract
Peculiarities of formation of a dissimilar aluminium-steel diffusion joint in solid-state activation of the surfaces, being joined, by gallium are considered. The effect of products of gallium-aluminium interaction on a local change in mechanical properties within the zone of a permanent joint is shown.
