Pore volume, fracture character, contaminants, alloying, concentration inhomogeneity, friction conditions, and other factors all have an impact on the mechanical and tribotechnical properties of powdered materials. Pores also have an impact on the speed of diffusion processes and the reduction of undercooled austenite.anti-resistance To explore porous iron characteristics, ultrapure iron that has been annealed in hydrogen was employed. a powder Porosity has a nonmonotonic effect on toughness fracture and tribotechnical characteristics.Unlike all other known dependencies derived from technical iron powders. The results of research have been revealed. The fact that the average dimension of porous changes during the process of porosity reduction by pressing and annealing cycles. Models of friction, wear, and fracture of pure porous iron were produced based on the examination of porous structure.
