METHOD OF PRODUCING COMPOSITE STEEL-ALUMINIUM LAMINAR MATERIALS Russian patent published in 2013 - IPC B22F7/04 B32B15/01 C23C24/06

Abstract RU 2501630 C1

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of laminar bimetallic composites. Proposed method comprise the following steps whereat dry aluminium powder is fed to strain region between dry aluminium powder band, said band and said powder are rolled together to reduction of 30-50% to produce aluminium coat on steel strip and thermal processing is effected. After heat treatment, said steel strip with aluminium coat applied thereon is cold-rolled to final reduction of 15-25% and rolled-drawn to height reduction of 20-30%.

EFFECT: production of laminar bimetallic composites with ductility that allows high degree of straining.
