Microstructure, Hardness, and Tribotechnical Properties of Low-Alloy Martensitic Steel with an Overequilibrium Nitrogen Content
Metallographic and tribological (under dry sliding friction conditions) investigations of low-alloy steel samples with an overequilibrium nitrogen content are performed after quenching in the temperature range from (Ac3 – 50) to (Ac3 + 250)°C. Metallographic analysis demonstrates that, as the quenching temperature increases, the grain size increases and the dispersion of the martensitic structure decreases. The results of tribological studies demonstrate that, after quenching in the temperature range (Ac3 + 100)–(Ac3 + 150)°C, the content of austenite saturated with carbon and nitrogen increases, which leads to a decrease in the coefficient of friction and an increase in the wear resistance.
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.
