Abstract
A combined method of electric contact heating and diffusion connection of steel-aluminum is proposed which makes; an essential effect on three-phase shaping conditions, provides better physical contact and contact surface cleaning, formation and conservation of solid setting units. Activation of contact surfaces is achieved more effectively and quickly than at mechanical and vacuum treatment. Formation of physical contact and setting corresponds to contemporary conceptions of solid body model and kinetics of development of connection strength by the data of the carried out tests. Mechanical testing is carried out in static and dynamic modes, structure and phase composition in steel-aluminum joint is determined.
