摘要： A process and apparatus for producing a spray of atomized metal droplets includes providing an apparatus that forms a spray of molten metal droplets, the apparatus including a metal source (24) and a metal stream atomizer, producing a stream (25) of liquid metal from the metal source, and atomizing the stream of liquid metal with the metal stream atomizer to form the spray of molten metal droplets (30). A controlled spray of atomized metal droplets is achieved by selectively varying the temperature of the droplets in the spray of molten metal droplets the step of selectively varying including the step of varying the flow rate of metal produced by the metal source, responsive to a command signal, and sensing the operation of the apparatus and generating the command signal indicative of the operation of the apparatus. The step of atomizing may be accomplished by directing a flow of an atomizing gas at the stream of liquid metal, and then selectively controlling the flow rate of the atomizing gas.

The rotating component (50) has a rotational axis (88), at least one rim member (52), at least one disk member (54), and at least one airfoil member (56). The rim and disk members (52,54) are welded together to define a first solid-state weld joint (82) lying in a first plane that is not parallel to the rotational axis (88) of the rotating component (50). The airfoil member (56) is welded to the rim member (52) to define a second solid-state weld joint (84) lying in a second plane that is not parallel to the rotational axis (88) of the rotating component (50). The rim member (52) is located in a radially outward direction from the disk member (54), and the airfoil member (56) is located in a radially outward direction from the rim member (52).

摘要： A method of forming a component from a gamma-prime precipitation-strengthened nickel-base superalloy so that, following a supersolvus heat treatment, the component characterized by a uniformly-sized grain microstructure. The method includes forming a billet having a sufficiently fine grain size to achieve superplasticity of the superalloy during a subsequent working step. The billet is then worked at a temperature below the gamma-prime solvus temperature of the superalloy so as to form a worked article, wherein the billet is worked so as to maintain strain rates above a lower strain rate limit to control average grain size and below an upper strain rate limit to avoid critical grain growth. Thereafter, the worked article is heat treated at a temperature above the gamma-prime solvus temperature of the superalloy for a duration sufficient to uniformly coarsen the grains of the worked article, after which the worked article is cooled at a rate sufficient to reprecipitate gamma-prime within the worked article.
