Influence of change of the ECAP tool channel geometry with inserted helix for strain hardening of the semis made of Al and Al alloys
Original language description
Technology ECAp is at present the most verified technology for of UFG and nano-materials. Dependencies of impact of geometry of the ECAP channel on gradual achievement of hoght degree of deformation are well know. For achievement of this hight deformation it is necessary to choose also an optimum type of passes through the ECAP tool in dependence on the formed material. The paper analys influence of changes of the deformation routes on magnitude of intezity of deformation and intenzity os stress. Chanheof route of deformation is realised by new geometry of horizontal channel, which consists of classical square cross section followed by helix, while the outlet has also a square cross section. On the semis made of Al we have achieved an increase of intenzity of deformation by 25-30% at individual passes.
