FIELD: process engineering.
SUBSTANCE: aluminium workpiece preliminary cladded by layer of commercial-grade aluminium is heated to temperature making (0.65-0.75) of aluminium melting temperature. Joint rolling of assembled pack consisting of cold steel and heated aluminium workpieces is carried out in one pass with 65 to 80%-squeezing and subsequent thermal treatment of composite metal. Prior to assembling the pack, steel workpiece contact surface is mechanically processed at specific pressure of (0.5 to 8.5) MPa to form crossed relief with its acute angle varying from 20 to 70 degrees, while profile irregularity height Rmax varies from 0.05 to 0.2 of the width of aluminium workpiece cladding layer.
EFFECT: higher strength, reliability and stability.
