Abstract
At present, different powder materials are produced and powder products of different composition are manufactured. The most widespread are iron powder materials used in mechanical engineering. These materials are characterized by high strength combined with a high level of ductility and toughness and low tendency to brittle fracture. The properties of these materials are mainly determined by the structure formed by sintering as a result of counterdiffusion and interaction of the initial components. Upon sintering, a heterogeneous and porous structure is formed. The effect of porosity and the interpore distance on the fracture toughness is analyzed. The results of the tests prove to be consistent with the phonon theory of discrete fracture.
