Phases and Equilibria in the W–C and W–Co–C Systems

摘要: The results of literature experimental and theoretical investigations phase equilibria in the W–C system crystal electronic structures WC, \(\mathrm{{WC}}_{1-x}\), \(\mathrm{{W}}_{2}\mathrm{{C}}\) tungsten carbides are generalized. sequence possible transformations associated with ordering lower hexagonal carbide is discussed preliminary. generalized information on ternary W–Co–C, which basis for synthesis hardmetals WC–Co, given. Methods WC–Co considered. Modern methods preparing nanocrystalline WC nanostructured hard alloys as well their properties.
