FIELD: metallurgy.
SUBSTANCE: method includes layered billet production in the form of a package and its subsequent rolling. The layered billet is produced by package welding in a solid phase in gas protected medium by rolling at a temperature of 420-470 °C with 20-30% relative compression. Then, the billet is subjected to multipass cold rolling upto the specified thickness at a relative compression 10-15% per pass and with interpass annealings at a temperature not higher than 500 °C after reaching the total degree of deformation more than 35%. Then a final heat treatment is carried out at a temperature of 500-800 °C with holding 1-4 hours.
EFFECT: mechanical and performance properties of the composite sheet material improving.
