Investigation of the Influence of High Speed Sintering Regimes on the Structure and Properties of WC Based Carbide Composites with High Entropy Bonding
The influence of the rate of sintering by electron beam sintering (EBS) and spark plasma sintering (SPS) methods on the formation of the microstructure and properties of a 90 wt % WC + 10 wt % FeCrNiWMo composite is studied. The effect of technological parameters of sintering on structure formation and phase composition of a metal ceramic composite with high entropy bonding is determined. The change in the stoichiometric composition of tungsten carbide after sintering the composite by the SPS method is investigated. The mechanical properties (strength, hardness, crack resistance, and compressive strength) of the samples sintered by the EBS and SPS methods are compared. It is found that the electron beam method is more promising than the spark-plasma method when sintering a metal ceramic composite with high entropy bonding under optimal conditions. The study results can be used in toolmaking and in the military industry for manufacturing armor piercing cores of ammunition for small arms.
期刊介绍：
Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
