Opis:
The paper presents the results of research on the effect of added iron powder from plasma cutting on the mechanical properties and structure of a composite rod based on aluminum powder. The iron powder came from plasma cutting of steel elements and was handed over by the enterprise “AK Anatol” from Żary. One of the ways to dispose of it is to use it as a filler in aluminum composite rods. Research shows that Fe can be distributed in aluminum evenly, and increase in mechanical properties is achieved at the expense of only a slight increase in density. The proposed system does not reduce the amount of waste produced by plasma cutting but finds a use for some of it. The sintering point of the powder required a strongly reducing atmosphere (Po2 < 10-50 atm) which seems virtually unachievable under laboratory conditions. The reinforcing mechanism is related to the fragmentation of the matrix aggregate particles and the uniform distribution of Fe particles in the aluminum matrix.

Opis:
This study aimed to develop Fe/Al multilayered metallic/intermetallic composites produced by hot pressing under an air atmosphere. Analyses were carried out on the composite plates made up of alternatively situated sheets of AA1050 aluminum alloy and DN04 low carbon steel, which were annealed at 903 K for 2, 5, and 10 h. Annealing was performed to obtain reaction layers of distinct thickness. The samples were examined using X-Ray diffraction and scanning and transmission electron microscope equipped with an energy-dispersive X-Ray spectrometer. To correlate the structural changes with mechanical properties, microhardness measurements in near-the-interface layers were performed. All the reaction layers grew with parabolic kinetics with η-Al5Fe2 intermetallic phase as the dominant component. After annealing for 5 and 10 hours, a thin sublayer of θ-Al13Fe4 phase was also detected.
