description: The theme of the final qualification work: "Research of the processes of deformation and sintering of copper powder PMS-1". This work is devoted to the study of deformation processes and the substantiation of the sintering modes of copper powders: 1. Consideration of the main methods for the production of copper powders; 2. Determination of the technological properties of copper powders (particle size distribution, bulk density, fluidity) of the PMS-1 and PMR-1 grades; 3. Investigation of the process of deformation of copper powders grades PMS-1 PMR-1 during cold static pressing; 4. Investigation of the sintering process of pressed samples and substantiation of the most rational sintering modes; 5. Investigation of the nature of deformation of sintered specimens during upset testing; 6. Manufacturing of samples and carrying out an experiment on equal-channel angular pressing (ECAP). The work was carried out on the basis of SPbPU, where the main material was collected: the results of experiments on pressing and sintering copper samples from powders of the PMS-1 and PMR-1 grades. As a result of the work, the main methods and technologies for producing copper powders were considered and analyzed, their technological properties were determined, and the processes of deformation and sintering of PMS-1 grade powder under various conditions were investigated. The most rational sintering modes were proposed, samples were obtained, and an experiment on equal-channel angular pressing (ECAP) was carried out.
