Abstract:
The monograph is devoted to solving the current scientific and technical problem of obtaining carbide steels of the Fe—Ti—C—B system with high wear resistance by improving the electric discharge treatment of mixtures of powders Fe, Ti using high-voltage electric discharge (HVED) in a hydrocarbon liquid and with subsequent spark-plasma sintering of the obtained charge. The theoretical conditions for the dispersion of powders and synthesis of solid phases during HVED processing are determined and correlation dependencies are found of dispersion and phase composition of the obtained powders from its parameters. A mechanism of high-voltage electric discharge synthesis of carbide phases during HVED treatment of powders in a hydrocarbon liquid are suggested. The phenomena that occur at high-voltage electric discharge in the dispersed system “hydrocarbon liquid-metal powder” are considered. The influence of a previous HVED processing of powder mixtures on the features of structure formation and basic physical and mechanical properties of carbide steels obtained using spark plasma sintering is substantiated. The results of experimental researches of the influence of high-voltage spark-plasma sintering modes on structure, phase composition, physical-mechanical and operational properties of metal-matrix composites consolidated from treated powder materials are generalized.
Intended for researchers and engineers, as well as for graduate students and university students who specialize in physics, chemistry, mechanics, materials science and metallurgy.
