摘要： Nickel-base alloys with improved elevated temperature creep and stress rupture lives are disclosed which are particularly useful for components in gas turbine engines exposed to high temperatures and stresses for long periods of time. The alloys are nickel-based consisting essentially of 0.005 to 0.15% C, 0.10 to 11% Mo, 0.10 to 4.25% W, from 12 to 31% Cr, 0.25 to 21% Co, up to 5% Fe, 0.10 to 3.75% Nb, 0.10 to 1.25% Ta, 0.01 to 0.10% Zr, 0.10 to 0.50% Mn, 0.10 to 1% V, l.8-4.75% Ti, 0.5 to 5.25% Al, less than 0.003% P, and 0.004 to 0.025% B. Key to the improvement of creep and stress rupture lives is the extremely low P content in conjunction with high B contents.

摘要： Processes, systems, and apparatuses are disclosed for forming products from atomized metals and alloys. A stream of molten alloy and/or a series of droplets of molten alloy are produced. The molten alloy is atomized to produce electrically-charged particles of the molten alloy by impinging electrons on the stream of molten alloy and/or the series of droplets of molten alloy. The electrically-charged molten alloy particles are accelerated with at least one of an electrostatic field and an electromagnetic field. The accelerating molten alloy particles are cooled to a temperature that is less than a solidus temperature of the molten alloy particles so that the molten alloy particles solidify while accelerating. The solid alloy particles are impacted onto a substrate and the impacting particles deform and metallurgically bond to the substrate to produce a solid alloy preform.

摘要： One non-limiting embodiment of an apparatus for forming an alloy powder or preform includes a melting assembly, an atomizing assembly, and a field generating assembly, and a collector. The melting assembly produces at least one of a stream of a molten alloy and a series of droplets of a molten alloy, and may be substantially free from ceramic in regions contacted by the molten alloy. The atomizing assembly generates electrons and impinges the electrons on molten alloy from the melting assembly, thereby producing molten alloy particles. The field generating assembly produces at least one of an electrostatic field and an electromagnetic field between the atomizing assembly and the collector. The molten alloy particles interact with the at least one field, which influences at least one of the acceleration, speed, and direction of the molten alloy particles. Related methods also are disclosed.
