Abstract
Tungstenless hard alloys produced from hard-alloy powders prepared by the electroerosive dispersion of wastes from TN20 tungstenless hard alloy are studied by X-ray diffraction to establish specific features of composition formation, as well as structures and properties of the materials in the chain “TN20 metal wastes (chemical and phase compositions)–electroerosive dispersion (chemical composition of the working liquid)–electroerosive hard-alloy powder (chemical and phase compositions)–spark plasma sintering–properties of tungstenless hard alloy (chemical and phase compositions).” The spark plasma sintering of the electroerosive hard-alloy powders under the conditions of fast heating and short working cycle suppresses the grain growth and favors the formation of the nonporous fine-grained structure.
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.
