| Popis: | Results are presented from a computer study of a promising method of high-rate plastic deformation – Multi-ECAP-Conform (M-ECAP-C) – for obtaining long ultrafine-grained semifinished products (wire rods) of aluminum alloy EN-AW 6101 in a single pressing cycle. It is shown that the distribution of cumulative strain in a semifinished product can be controlled by changing the geometry of the tool. The study examined three geometric variants for the outlet section of the pressing channel and used the results to develop an efficient new channel geometry for pressing by the M-ECAP-C method. The new channel shape makes the strain state of semifinished products more uniform during the stage of stable flow of the material, lowers the pressing forces, and reduces the tensile stresses in the deformation zone. |
