Abstract: A first pre-sintered body composed of a powder made of a first Ni-based alloy is prepared, and a second pre-sintered body composed of a powder made of a second Ni-based alloy is prepared. Subsequently, the first and second pre-sintered bodies are positioned to face each other across a predetermined gap, and a joining material made of a Ni-based alloy having a lower liquidus temperature than the first and second Ni-based alloys is placed in a space that adjoins the first and second pre-sintered bodies and to which the gap opens. After the placing of the joining material, the first and second pre-sintered bodies are heated to melt the joining material, fill the gap with the molten joining material, and subsequently turn the first and second pre-sintered bodies into first and second sintered bodies, respectively.

Abstract: An apparatus for dispensing build powder and support powder, in a sequence of layers, and having a frame and a container. Also, a build powder pourer is at least partially filled with build powder and a support powder pourer at least partially filled with support powder, each of the pourers having a dispensing opening and a dispensing plug, controllably covering the dispensing opening. Further, a pourer-movement and dispensing plug-actuating assembly is supported by the frame over the container and includes a movement element that is selectively attachable to the build powder pourer and alternately to the support powder pourer and also capable to controllably move an attached pourer in three orthogonal dimensions and to control the dispensing plug. In addition, at least one docking station for holding a first one of the pourers; and a computing assembly controls the pourer-movement and dispensing plug-actuating assembly to create a target shape.

Abstract: The invention is a process for manufacturing a nano aluminum/alumina metal matrix composite and composition produced therefrom. The process is characterized by providing an aluminum powder having a natural oxide formation layer and an aluminum oxide content between about 0.1 and about 4.5 wt. % and a specific surface area of from about 0.3 and about 5 m2/g, hot working the aluminum powder, and forming a superfine grained matrix aluminum alloy. Simultaneously there is formed in situ a substantially uniform distribution of nano particles of alumina. The alloy has a substantially linear property/temperature profile, such that physical properties such as strength are substantially maintained even at temperatures of 250° C. and above.

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: 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%.
