20160107362 | METHOD FOR EXTRUDING PLASTICIZED POWDERED MATERIALS (VARIANTS) AND DEVICE FOR IMPLEMENTING SAME (VARIANTS) - A method for extruding plasticized powdered materials includes forming a part blank from a material and forcing the part blank along an extrusion axis through a deformation channel having a variable cross-section. As the material is forced through the deformation channel, it is subjected to the simultaneous effect of oppositely signed cyclic drawing, shear and torsional strains as a result of the creation in the material of two oppositely signed cyclic compressive strains which are orthogonal to the extrusion axis and act in antiphase. The maximum increases in one of these compressive strains are set for the material in a plane which passes through the extrusion axis. The maximum increases in the second of these compressive strains are set for the material at the inlet and outlet of the deformation channel, orthogonal to the plane which passes through the extrusion axis. As the material is forced through the deformation channel, the directions of the maximum increases in the second compressive strain are changed by the rotation thereof about the axis of the channel according to any smooth periodic function having a period equal to the length of the deformation channel and an amplitude equal to 15-75°. | 04-21-2016 |
