    摘要： Methods for manufacturing an article include providing a three-dimensional computer model of the article and providing a metal alloy in powdered form. The metal alloy is an aluminum-iron-vanadium-silicon alloy. The powdered form includes a grain size range of about 5 to about 22 microns and a d50 grain size average of about 10 to about 13 microns. The methods further include, at a binder jet printing apparatus, supplying the metal alloy and loading the three-dimensional model, and, using the binder jet printing apparatus, manufacturing the article in accordance with the loaded three-dimensional model in a layer-by-layer manner with the supplied metal alloy. A liquid binder is applied at each layer, and each layer has a thickness of about 10 to about 150 microns. The methods avoid remelting of the metal alloy and avoid metal alloy cooling rates of greater than about 100 °F per minute.

    摘要： Additive Manufacturing Quality Management (AMQM) systems (10) and methods (60) are provided, which enhance quality control across Additive Manufacturing (AM) supply chains from which AM components are obtained. In various embodiments, the AMQM system includes an AM machine (20) utilized to produce AM components (40) in accordance with AM design data (34). A first sensor (42) is coupled to the AM machine and, during fabrication of AM components (40) by the AM machine (20), captures sensor readings pertaining to the AM fabrication process. When executed by a processor (44), computer-executable code causes the AMQM system to: (i) compile part-specific sensor profiles (110, 112, 114) from sensor readings captured by the first sensor (42) during fabrication of the AM components (40), and (ii) generate user notifications indicating whether remedial action should be performed for any of the AM components (40) based, at least in part, on conformance of the part-specific sensor profiles (110, 112, 114) with a baseline sensor (42) profile corresponding to the AM design data (34).

    摘要： A fuel injector assembly (230) includes a fuel injector (310) and a fuel injector shroud (330) housing the fuel injector. The fuel injector includes a body (314) and a nozzle (316) coupled to the body. The fuel injector shroud includes a swirler device (370) defining a center opening (372) proximate to the nozzle of the fuel injector and a plurality of swirler holes (374) surrounding the center opening, a body section (350) with an air inlet (356) configured to admit a flow of air into the fuel injector shroud and a dome section (354) defining a mount for securing the swirler device to the body section, and at least one interior rib (561) positioned on an interior surface of the dome section configured to direct the flow of air to the swirler holes of the swirler device such that the flow of air exiting through the swirler is mixed with the flow of fuel exiting the nozzle.
