Abstract: A metal article including an at least partially heat treated metal composition, and a method for treating the metal article are provided. The method for treating the metal article may include heating the metal article to a first holding temperature of about 690° C., and holding the metal article at the first holding temperature for at least about 10 hours. The method may also include cooling the metal article from the first holding temperature to a first cooling temperature of about 65° C. or less. The method may further include heating the metal article to a second holding temperature of about 615° C., and holding the metal article at the second holding temperature for at least about 10 hours. The method may also include cooling the metal article from the second holding temperature to a second cooling temperature of about 65° C. or less.

Abstract: A method for fabricating a turbomachine component including a metal alloy with a layering device is provided. The method for fabricating the turbomachine component may include combining two or more elemental powders to form a powdered material. The method for fabricating the turbomachine component may also include forming a first metal alloy layer of the turbomachine component on a substrate. Forming the first metal alloy layer on the substrate may include melting a first portion of the powdered material to a first molten material with a heat source, mixing the first molten material with the heat source, and cooling the first molten material. The method for fabricating the turbomachine component may further include forming a second metal alloy layer of the turbomachine component on the first metal alloy layer, and binding the first metal alloy layer with the second metal alloy layer.
