Properties of interparticle splicing surface density during powder bodies sintering
Incoming article date: 12.09.2022This article proposes an experimental determination of the density of the interparticle fusion surface during sintering of hot-deformed powder materials. The study analyzes the physics of the processes of forming microstructures of splicing surfaces at various stages of producing powder materials. The peculiarities of deformation processes in the formation of materials by hot pressure treatment are considered and physical changes that undergo powder grains are investigated. The nature of the boundaries of the splicing surfaces on the investigated objects, as well as the process of pore healing during compaction of molds based on steel from two types of charge based on coarse and fine iron powder with different porosity are traced.
Keywords: physics of processes, quantitative characteristics, surface area of splicing, specific surface of splicing, hot-deformed powder blanks, structure formation, microstructures, surface deformation, pore healing, particle size
