METHOD OF MANUFACTURE OF FLAT BIMETALLIC MATERIALS Russian patent published in 1997 - IPC

FIELD: electrical, electronic and aircraft industries; production of household appliances; plastic metal working. SUBSTANCE: proposed method comes to preparation of contact surfaces and subsequent combined deforming of metals. Smaller thickness metal is arranged at side of tool having higher drive speed. When deforming flat blanks of connected metals by tools working at different speed arrangement of blanks relative to tool exerts considerable action on distribution of interlayer deformations. Most favorable from the point of view of provision of strong connection of layers is positioning of smaller thickness metal as stated above. EFFECT: increased strength of connection of layers by increasing level if interlayer deformations of connected metals.
