description: Theme of the final qualification work: âResearch of the processes of forming billets of copper powders for equal-channel angular extrusionâ. This work is devoted to the research of the processes of forming copper billets for equal-channel angular extrusion. Tasks that were solved during the study: 1. Research of compaction of copper powders. 2. Development of sintering modes for copper billets. 3. Analysis of the process of sintering billets, carried out in different modes. 4. Research of the ECAE process for copper powder blanks obtained by various sintering modes.The work was carried out on the basis of Peter The great Polytechnic University and Â«CompositÂ», where the forming and sintering of blanks made of PMS-1 copper powder at temperatures of 850 and 950 Â°C. Cooling was carried out in air, in the oven and in water. Calculations of shrinkage, density, porosity, and mass loss after sintering were performed, and the dependences of density, porosity, and shrinkage on the parameters of pressing and sintering were constructed based on the obtained data. As a result, a rational sintering mode was selected, which determines the properties and parameters of copper billets for equal-channel angular extrusion.
