Development of structure at Extrusion of a Strip of Made of Cu though the DRECE Machinery

Popis výsledku v původním jazyce

Achievement of ultra-fine grained (UFG) structure in the strip of sheet is one of the basic problems of the current research in the field of forming. Contrary to bulk forming (processes ECAP, HTP, Conform, etc.), it is much more difficult to achieve highdegree of deformation during 5 to 7-8 pasess by the processes ARB, C2S2 (DCAP). At extrusion of the strip of sheet with use of the process C2S2 the refinement of structure (e.g., in the sheet made of Al) is visible only after 12-15 passes. This is givenby the possibility of use of only one type os passes designated in literature as "C" (pass with turning of material by 180°C). This creates smaller nimber of passes on structure refinement of a strip of Al sheet on the brand new prototype equipment, DRECE (Dual Rolling Equal Channel Extrusion). The proess was methematically simulated and resulated were mutually compared.
