METHOD TO PRODUCE ALUMINIUM COMPOSITE MATERIAL WITH ULTRA-FINE STRUCTURE

摘要

FIELD: machine building.SUBSTANCE: method involves production of a blank by making a package from aluminium alloy plates and intermediate layers of composite component, heating of the package and applying of compression force to it to provide for diffusion welding, afterwards the blank is subject to further processing by intensive plastic deformation by all-round forging with successive change of the deformation direction in three coordinate axes of the blank and with stepwise decrease of the deformation temperature until the accumulated deformation level in the blank volume is at least 3.EFFECT: invention allows for the production of aluminium composite material with ultra-fine structure having improved performance characteristics.1 ex
