“…Correct choice of deformation angle (108° or 113°), the magnitude of which was determined by mathematical simulation, is a critical parameter influencing the resulting mechanical properties and microstructure of the formed material. The given method enables the forming of sheets with a length of 1000 to 2000 mm, a width of 58 mm and a thickness of 2 mm [3][4][5][6][7][8][9][10]. The principle of the DRECE method is shown in Figure 1.…”

The DRECE method is a very promising method for forming sheet metal sheet using the severe plastic deformations (SPD) principle. The DRECE method is characterized by the continuous extrusion of the sheet metal strip by the forming die, which creates a forming angle of 108 ° in the deformation zone. In the case of materials formed by a given method, there is a substantial increase in the mechanical properties, in particular the yield strength, already after the first pass through the forming device, while maintaining sufficient ductility of the materials. This fact is very important for the subsequent use of the method in industrial practice. In order to study the possibility of applying the DRECE method in industrial practice, this work presents proposals for design solutions for industrial use. The proposed design solution is also supplemented by mathematical simulations of the forming process.

“…Among the currently developed technologies of plastic deformation of metallic materials, severe plastic deformation (SPD) methods are worth to mention [5][6][7]. This plastic deformation technologies consists of transforming the micrometric structure of coarse-grained materials into ultra-fine (UFG with grain size in range of 100-1000 nm) and/or nanometric materials (grain size < 100 nm) by re-organizing the dislocation structure created during plastic deformation [8][9].…”

The article deals with the grain refinement and microstructure evolution of AZ61 magnesium alloy subjected to sever plastic deformation (SPD) by ECAP (Equal Channel Angular Pressing) process. The commercial hot extruded AZ61 alloy subjected to severe plastic deformation possesses a two-phase microstructure consisting of solid solution matrix and massive  -phase Mg17Al12 distributed mostly at grain boundaries. Based on selected area diffraction and electron back scattered diffraction applied to a sample after the third pass, it can be concluded that plastic deformation induced by ECAP occurs mainly by slip mode forming a high density network of dislocation inside the grains. The grains size was significantly refined to 1.4 μm after the third pass of ECAP. The refinement of grain size is probably due to polygonization process associated with formation of high angle grain boundaries due to dislocations rearrangement. Mg17Al12 precipitates of size scattered from 100 to 200 nm and also the primary precipitates of Al6Mn phase were observed in this alloy.

The DRECE method is a progressive method for forming sheet metal strips using the principle of severe plastic deformation (SPD). The DRECE method is characterized by extruding the sheet metal strip with a forming device which creates a forming angle of 108 ° in the deformation zone. During the practical verification of the DRECE method, it was found that the materials formed by the method show a significant increase in mechanical properties after the first pass through the forming equipment while maintaining sufficient ductility of the materials. With each subsequent pass of the material through the forming device, the mechanical properties increase. For the subsequent industrial use of the DRECE method, the key technological parameter of the forming equipment is the feed speed of the sheet metal strip. At present, the forming device makes it possible to regulate the feed speed of the sheet metal strip in the range of 10 - 100 mm / s. The device allows continuous sensing and recording of torque, extrusion force and feed rate of the sheet metal strip during the forming process. These facts are very important for the subsequent use of the method in industrial practice.
