Provided is a low binder high density cemented carbide composition for neutron shielding including a ceramic hard phase composed of tungsten carbide (WC), sub-stoichiometric ditungsten carbide (WC), or a combination thereof, and a low weight iron (Fe)-chromium (Cr) based metallic binder phase from about 0.02 wt. % to about 2.75 wt. % based on a total weight of the cemented carbide composition. A Cr weight of the Fe—Cr based metallic binder phase may be present from about 5 wt. % to about 16 wt. % based on a total weight of the Fe—Cr based metallic binder phase. Associated methods of manufacturing a sintered low binder high density cemented carbide for neutron shielding are further presented.

Low binder high density cemented carbides for neutron shielding applications

Provided is a cemented carbide composition having a hard phase made of tungsten carbide (WC) as a first hard phase component and at least one second hard phase component selected from the group consisting of tantalum carbide (TaC), niobium carbide (NbC), and mixtures thereof, and a binder phase made of at least one binder component selected from the group consisting of cobalt (Co), nickel (Ni), and mixtures thereof. Also provided is a cemented carbide composition having a hard phase made of WC as a hard phase, NbC as an anti-galling phase, and TaC as a toughness improver, and a binder phase made of at least one binder component selected from the group consisting of Co, Ni, and mixtures thereof. Associated methods of producing the cemented carbide compositions and tools incorporating the same are additionally contemplated.

Cemented carbide compositions

Provided is a corrosion and erosion resistant cemented carbide for high demand including, for example, oil and gas flow applications. The cemented carbide grade may include, for example, including the following constituents Co, Ni, Cr, Mo and WC. The binder phase content of the cemented carbide is between 5.1 to 7.5 wt %. The wt % of Co in the cemented carbide may be less than the wt % of Ni.

Cemented carbide for high demand applications

Provided is a corrosion, erosion and wear resistant cemented carbide for high demand applications including, for example, use as a component within oil and gas production. The cemented carbide includes a hard phase and a binder phase. The cemented carbide may include, for example. Ni, Cr and Mo. The binder phase content of the cemented carbide is between 7 to 11 wt %. The WC of the cemented carbide may have an average grain size of from 0.1 to 2 &#x3bc;m.
