    Abstract: Hardmetal compositions each including hard particles having a first material and a binder matrix having a second, different material comprising rhenium or a Ni-based superalloy. Tungsten may also be used a binder matrix material. A two-step sintering process may be used to fabricate such hardmetals at relatively low sintering temperatures in the solid-state phase to produce substantially fully-densified hardmetals. A hardmetal coating or structure may be formed on a surface by using a thermal spray method.

    Abstract: A well production assembly includes a production tree which has a lateral production passage extending laterally from a vertical bore of the tree. A tubing hanger, also having a lateral production passage, lands in the tree, with the lateral passages registering with each other. The junction of the lateral passages has flat, tapered sealed areas which mate with one another. An annulus passage extends vertically through the tubing hanger offset from and parallel to the tubing hanger vertical production passage. The annulus passage also has a lateral passage which registers with the lateral passage formed in the tree. The annulus lateral passages have a flat seal area at their junction. The tubing hanger has a downward facing hydraulic connector which registers with an upward facing hydraulic connector located on a shoulder formed in the bore. Once mated, the connectors provide hydraulic or other auxiliary fluid communication to downhole equipment.

Each blade comprises a central metal core at least partly surrounded by solid infiltrated matrix material. A method of manufacturing such a drill bit includes the steps of forming a main body part from metal, applying to the outer surface of the main body part a coating layer of wax which liquefies at elevated temperature, applying to the coated body part mold-forming material to provide a self-supporting mold surrounding the coated body part, and raising the temperature of the body and surrounding mold sufficiently to liquefy the coating material. The liquefied coating is then drained from the mold, and the cavities left by the coating material are packed with powdered matrix material, which is then infiltrated with a binder alloy at elevated temperature to form a solid infiltrated matrix layer, on the bit body part, corresponding to the layer of wax previously applied.

    Abstract: In forming an article, such as a turbine blade, of metal powder, a container is first formed by electroplating a thin layer of metal over a pattern having a configuration which corresponds to the configuration of the article. The pattern is then removed to leave a container having a cavity with a configuration corresponding to the configuration of the article. The container is filled with metal powder and sealed. The container is then at least partially enclosed with a rigid body of fluid permeable material having inner side surface areas disposed in abutting engagement with the container. Heat and fluid pressure are transmitted through the rigid body to compact the container and metal powder. The fluid pressure causes the side walls of the container to move away from the inner side surfaces of the rigid body of fluid permeable material. As this is occurring, the rigid body of fluid permeable material supports the container and holds it against excessive deflection under the influence of stresses induced in the container.
