description: The given work is devoted to the study of the possibility of implementing equal-channel angular pressing of copper powder without complicating the technological process. Tasks that were solved during the research: 1. Conducting a literature review of existing processes of deformation accumulation and the resulting properties in various materials. 2. Conducting an experimental study of the process of deformation of a porous sintered billet in the conditions of ECAP. 3. Identification of the reasons for violation of the integrity of the porous material and recommendations for the technological process of preparing porous blanks for RCU-pressing. 4. To evaluate the influence of various factors on the possible violation of the integrity of the porous sintered billet in the conditions of ECAP using computer modeling. As a result of experimental studies, various defects were obtained after the ECAP process, such as cracks, pores, and oxides on the surface. It was proposed to improve the technology of obtaining samples, thereby increasing its density. And also increase the temperature of the rcup process to 200 Â°C. The calculation results showed that initially the denser billet passes the turning part of the channel more easily. With an increase in temperature, the overall stress level (including tensile) in the material decreases, the output part of the channel is better filled, and the workpiece is easier to rotate.
