Abstract
This paper reports the preparation of cast iron aluminides from thermite-type highly exothermic mixtures at atmosphere pressure in air. We have studied general aspects of combustion during the synthesis process and evaluated the ingot yield of the synthesized iron aluminides and the relative weight loss of the starting mixture components and final products in the combustion process. The chemical and phase compositions of three synthesized cast phase-pure iron aluminides—Fe3Al, FeAl, and Fe2Al5—have been determined, their microstructures have been studied, and their microhardness has been measured.
期刊介绍:
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
