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.

Abstract: 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.

Abstract: A cemented carbide suitable as a high performance hard metal material for wire drawing of high-tensile strength alloys is provided. The cemented carbide may include a relatively low binder content with additives Cr, Ta and/or Nb to provide high wear and corrosion resistance, high thermal conductivity, high hardness and a desired hardness to fracture toughness correlation.

Abstract: Provided is a cemented carbide suitable for use as a material in the manufacture of a punch for metal forming and in particular for the manufacture of metal beverage cans. The cemented carbide may include a hard phase that includes WC, a binder phase and a gamma phase. The gamma phase may include metal carbides in combination with metal nitrides or metal carbonitrides. A quotient of the average grain size of WC/the average grain size of the gamma phase may be in a range of from 0.5 to 1.5.

Abstract: Provided is a wear resistant, sintered body made of a binderless carbide, cermet or cemented carbide, e.g., WC, W2C and/or eta-phase, with a grain size less than 6.0 ?m, and less than 6% binder phase (e.g., Co—Ni—Fe). At least some working surfaces of the sintered body are surface treated with a boron yielding method including applying a low viscosity liquid medium having boron or aluminum content and heating at 1200° C. to 1450° C. under a pressure less than atmospheric pressure or a hydrogen containing atmosphere to from a hardness gradient with an increased hardness of the treated working surfaces of at least 50 to 200 HV5 and favorable compressive stresses in a surface zone that gives a tougher working surfaces of the boronized sintered bodies.
