Abstract—In a metallurgical method of producing metal matrix composites, the effect of ultrasound on a melt is shown not to affect the phase composition of the diffusion zone formed as a result of heterogeneous reactions at the interface of aluminum with iron-based alloys. At a fixed temperature, an applied acoustic vibration frequency of 18–20 kHz, and an amplitude of 10–15 μm, the diffusion zone thickness is found to increase due to the formation of the FeAl3 intermetallic compound, which actively separates from the interface into the melt, and to the fraction of the surface on which it is present as a continuous layer.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
