Low binder high density cemented carbides for neutron shielding applications

Abstract

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 (W2C), 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.
