摘要： Systems and methods for identifying and mitigating gas turbine component misalignment using virtual simulation are disclosed herein. An example method may include capturing data associated with a first nozzle segment and a second nozzle segment of a gas turbine. The method may also include creating, based on the captured data, a virtual representation of the first nozzle segment and the second nozzle segment. The method may also include determining that a misalignment exists in a connection between the virtual representation first nozzle segment and the virtual representation of the second nozzle segment. The method may also include identifying, based on the determination that the misalignment exists, a third nozzle segment. The method may also include determining that a connection between a third nozzle segment and the first nozzle segment includes a smaller misalignment.

摘要： A grain starter for use in solidification of molten metallic material forming an article having a directional grain structure and a method for solidifying an article having a directional grain structure with a substantial absence of stray grains. The grain starter comprises a grain-starting material that initiates grain growth in the molten metallic material in a preselected crystallographic direction. The grain-starting material has a melting temperature higher than the metallic material forming the article lest the grain starter be modified by contact with the molten material. The grain starter further includes a feature that modifies heat transfer characteristics of the metallic material in contact with it in order to produce an article having grains oriented in the preselected crystallographic orientation and modifies the profile of the advancing solidification front. The article is substantially free of stray grains not oriented in the preselected crystallographic direction.

摘要： A process for forming a diffusion coating on a substrate is disclosed, including preparing a slurry including a donor metal powder, an activator powder, and a binder, and applying the slurry to the substrate. The slurry is dried on the substrate, forming a slurry layer on the substrate. A covering composition is applied over the slurry layer, and the covering composition is dried, forming at least one covering layer enclosing the slurry layer against the substrate. The slurry layer and the at least one covering layer are heated to form the diffusion coating on the substrate, the diffusion coating including an additive layer and an interdiffusion zone disposed between the substrate and the additive layer.

摘要： A modified alloy is disclosed including a base alloy composition and an additive gamma prime antioxidant. The base alloy composition includes a concentration of a gamma prime antioxidant less than an effective concentration of the gamma prime antioxidant. The additive gamma prime antioxidant is intermixed with the base alloy composition to form the modified alloy, preferentially segregating to a gamma prime phase of the modified alloy and increasing the concentration of the gamma prime antioxidant to be at least the effective concentration of the gamma prime antioxidant. The effective concentration imparts reduced oxidation susceptibility of the gamma prime phase. An article is disclosed including the modified alloy. A coated article is disclosed including a coating disposed on a surface of an article having the base alloy composition. The coated article includes a reduced stress accelerated gamma prime oxidation static crack growth susceptibility in comparison with the base alloy composition.
