Abstract: A tungsten sintered compact sputtering target and film are provided. The purity of the tungsten is 5N (99.999%) or more and the content of impurity carbon in the tungsten is 5 wtppm or less. The tungsten film, which is sputter-deposited by using the tungsten sintered compact sputtering target, has a low specific resistance due to the reduced carbon content in the tungsten target.

Abstract: A method of forming a supporting substrate for a cutting element comprises forming a precursor composition comprising discrete WC particles, a binding agent, and discrete particles comprising Co, Al, and one or more of C and W. The precursor composition is subjected to a consolidation process to form a consolidated structure including WC particles dispersed in a homogenized binder comprising Co, Al, W, and C. A method of forming a cutting element, a cutting element, a related structure, and an earth-boring tool are also described.

Abstract: Embodiments of the invention relate to polycrystalline diamond compacts (“PDC”) exhibiting enhanced diamond-to-diamond bonding. In an embodiment, PDC includes a sintered substantially single-phase polycrystalline diamond (“PCD”) body consisting essentially of bonded-together diamond grains exhibiting a morphology different than that of a PCD body formed by sintering diamond crystals. A substrate is bonded to the sintered substantially single-phase PCD body. Other embodiments are directed to methods of forming such PDCs, and various applications for such PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.

Abstract: Cutting elements having accelerated leaching rates and methods of making the same are disclosed herein. In one embodiment, a method of forming a cutting element includes assembling a reaction cell having diamond particles, a non-catalyst material, a catalyst material, and a substrate within a refractory metal container, where the non-catalyst material is generally immiscible in the catalyst material at a sintering temperature and pressure. The method also includes subjecting the reaction cell and its contents to a high pressure high temperature sintering process to form a polycrystalline diamond body that is attached to the substrate. The method further includes contacting at least a portion of the polycrystalline diamond body with a leaching agent to remove catalyst material and non-catalyst material from the diamond body, where a leaching rate of the catalyst material and the non-catalyst material exceeds a conventional leaching rate profile by at least about 30%.

Abstract: A tool and a method of making the tool are disclosed. The tool includes a superabrasive compact, for example, a volume of silicon carbide diamond bonded composite, directly bonded to a tungsten carbide body during sintering. The green body may have a recess with a complementary shape to the superabrasive compact, whereby after inserting at least a part of the superabrasive compact within the recess and sintering, the tungsten carbide body and the recess shrink to form an interference fit therebetween.
