Abstract
Solid-phase weldability of micro-dispersed composite material AMg5 + 27 % Al₂O₃ by using rapidly solidified interlayer of eutectic alloy Al + 33 % Cu was studied. It was established that application of the rapidly solidified strip as an interlayer activates the mating surfaces and allows decreasing the temperature and time of diffusion welding of AMg5 + 27 % Al₂O₃ material. Employment of the techniques that accelerate diffusion processes in a butt joint (forced deformation, thermal cycling) made it possible to reduce the interlayer thickness to its almost complete dissolution and improve shear strength of the welded joint to the base metal strength level.
