Abstract
The possibility of obtaining a composite material from a ferroalloy based on silicon, aluminum, and zirconium nitrides using self-propagating high-temperature synthesis is considered. It is shown that introducing up to 35% of a nitrogen-containing additive on the basis of ferroalumosilicozirconium to the initial ferroalloy leads to an increase in the nitrogen fraction, emission of the basic nitride phases in combustion products, deceleration of the combustion wave front, and reduction of the maximum combustion temperature. It is revealed that adding more than 20% of a preliminary nitrided material makes it possible to stabilize the combustion wave front propagation conditions and to obtain combustion products with a macroscopically homogeneous composition. Under the conditions of natural filtration of nitrogen, combustion of a powder mixture based on ferroalumosilicozirconium and a nitrided material yields a composite consisting of AlN, Si3N4, ZrN, and \(\alpha\)-Fe phases.
期刊介绍：
Combustion, Explosion, and Shock Waves a peer reviewed journal published in collaboration with the Siberian Branch of the Russian Academy of Sciences. The journal presents top-level studies in the physics and chemistry of combustion and detonation processes, structural and chemical transformation of matter in shock and detonation waves, and related phenomena. Each issue contains valuable information on initiation of detonation in condensed and gaseous phases, environmental consequences of combustion and explosion, engine and power unit combustion, production of new materials by shock and detonation waves, explosion welding, explosive compaction of powders, dynamic responses of materials and constructions, and hypervelocity impact.
