摘要： An improved X-ray tube target comprises a refractory metal target substrate and a refractory metal focal track applied to the target substrate by a tape casting process. The X-ray tube target comprises a refractory metal target substrate and a refractory metal focal track formed on the target substrate to form a focal track/target substrate interface plane that varies less than about ±0.13 mm.

摘要： Shaped bodies containing particulate iron materials, such as cast pellets, briquettes and the like, with sufficient strength to withstand temperatures of up to at least 1000° C. can be obtained by using a fully hydrated high-alumina cement as the binder. The strength of the pellets at elevated temperatures can be further enhanced by adding small amounts of bentonite, silica fume or other suitable supplementary cementing materials, and super plasticizer. The iron particulate materials, typically having a size range of from about 0.01 mm to 6 mm, include ore fines, sinter fines, BOF and EAF dusts, mill scale, and the like. Powdered carbonaceous material, such as ground coal or coke, may also be added to the pellets. The shaped bodies are suitable for use in blast furnaces, basic oxygen furnaces, and in DRI processes.

摘要： Although MIM (metal injection molding) has received widespread application, aluminum has not been widely used for MIM in the prior art because of the tough oxide layer that grows on aluminum particles, thus preventing metal—metal bonding between the particles. The present invention solves this problem by adding a small amount of material that forms a eutectic mixture with aluminum oxide, and therefore aids sintering, to reduce the oxide, thereby allowing intimate contact between aluminum surfaces. The process includes the ability to mold and then sinter the feedstock into the form of compacted items of intricate shapes, small sizes (if needed), and densities of about 95% of bulk.
