Abstract: In an embodiment, an apparatus for forming a metal component from alloy powder includes a powder-based layer-by-layer directed energy beam additive manufacturing system, a primary directed high energy beam, configured to raise a temperature of the alloy powder to or above the melting point of the alloy powder. A secondary directed low energy beam configured to raise the temperature of the alloy powder to or above a sintering point of the alloy powder without reaching the melting point of the alloy powder. The apparatus further includes a sintered region on the surface of an alloy powder layer previously produced by the secondary directed low energy beam and a solid region forming a portion of the metal component that was solidified from a molten pool on the surface of the alloy powder layer adjacent to the first sintered region having been produced by the primary directed high energy beam.

Abstract: A multi-component fastener is provided having a body and a sleeve. The body has a shank that extends lengthwise between a head and a distal end. The shank includes a first outer surface. The body includes a first material. The sleeve has a wall defined by an outer surface and an inner surface. The inner surface defines an interior cavity. The wall extends lengthwise between a first end and a second end. At least a portion of the sleeve outer surface contiguous with the first end is threaded. The sleeve includes a second material that is dissimilar to the first material. A portion of the shank including the distal end is disposed within the interior cavity of the sleeve. The sleeve and the shank are fixed to one another.

Abstract: A method of forming an object includes installing multiple foil drums within a processing chamber of an ultrasonic consolidation system. The multiple foil drums each include different materials than the other foil drums. The multiple foil drums are positioned so that one of the foils is selected to be placed on top of the build platform. The selected foil is welded onto the build platform or onto a previously processed layer. A portion of the welded foil is then cut. The multiple foil drums are retracted away from the build platform. The portion of the welded foil that was just cut is then consolidated to the object. The build platform is incrementally lowered before the process is repeated to form the next layer of the object.
