    Strength of functionally designed cellular cemented carbides produced by coextrusion

    In an effort to improve the wear characteristics of petroleum drill bit inserts, a series of cemented carbide materials with a functionally designed cellular (FDC) architecture were fabricated by a coextrusion...

    A dual composite of WC-Co

    Hardness, fracture toughness, and wear resistance are strongly inter-related properties of cemented tungsten carbide. Higher hardness usually dictates higher wear resistance but at the cost of fracture toughne...

    Gravitational effects on grain coarsening during liquid-phase sintering

    Grain growth in liquid-phase sintering (LPS) is often treated as an extension of Ostwald ripening. However, the inherent grain contact at high solid contents leads to coalescence and other conflicts with most ...
