FIELD: technological processes.
SUBSTANCE: after surfaces of steel and two brass tapes have been prepared, plating is carried out by means of their combined plastic deformation with application of lubricant. Thickness of initial materials is selected provided that thickness of brass layer on every side of steel base makes 3÷40% from its thickness. Plating is carried out with extent of deformation from 50 to 70% with application of lubricant. Final cold rolling is carried out with odd number of steps with the rate of 0.5÷5.0 m/s. Annealing of prepared composition is done at the temperature of 640÷770°C. Temper rolling is carried out in single stage with pressing up to 1.5% with the rate of 1.5÷5.0 m/s.
EFFECT: high level of strength and plasticity, required strength and structure, high performance characteristics and consumer properties of composition.
