Results of investigations of specifics of processes of structure and phase formation in joints of dissimilar metals with a limited mutual solubility (St.3 + aluminium), made by pressure welding using different temperature conditions of welding deformation (conventional and inertia friction welding and explosion welding) are presented.
Keywords: friction welding, explosion welding, steel- aluminium joints, structural parameters, strengthening, mechanical properties, phase precipitations, dislocations
