Abstract
The results on the effect of introduction of iron aluminide of various chemical and phase compositions on the structure and mechanical properties of powdered carbon steel and tin bronze are presented. It is shown that the introduction of 0.5 % single-phase iron aluminide Fe3Al leads to an increase in the strength of powdered carbon steel by 30–40 MPa, of biphase Fe2Al5 –FeAl3 – by 80–90 MPa, 1 % – to an insignificant decrease in strength. When a single-phase iron aluminide in the powder steel structure is introduced, a decrease in cementite, differentiation is observed, aluminum diffusion into the substrate occurs, and when two-phase aluminide is introduced, the structure griding occurs as well. It is established that the introduction of 0.5 % single-phase iron aluminide into powder bronzes makes it possible to increase its strength by 80– 100 MPa, two-phase – leads to a reduction in strength by 40–50 MPa. Introduction of 1 % single-phase iron aluminide and 0.2–1 % biphasic aluminide causes a change in the morphology of the structure of the powder bronze due to alloying the copper with aluminum and iron.
