METHOD OF PRODUCING COMPOSITE STEEL-ALUMINIUM LAMINAR MATERIALS Russian patent published in 2011 - IPC B32B15/01 B32B15/18 B32B15/20

Abstract RU 2435671 C1

FIELD: process engineering.

SUBSTANCE: invention relates to production of laminar composite steel-aluminium materials. Steel sheets are pre-stacked into cores and impregnated aluminium melt with 0.5-5 wt % of titanium at melt temperature of 720-850°C.

EFFECT: flux application increases strength of intermediate intermetallic layer formed on steel-aluminium interface.
