Abstract: Various methods are disclosed for additively manufacturing a feedstock material to create an AM preform, wherein the AM preform is configured with a body having an internal passage defined therein, wherein the internal passage further includes at least one of a void and a channel; inserting a filler material into the internal passage of the AM preform; closing the AM preform with an enclosure component such that the filler material is retained within the internal passage of the AM preform; and deforming the AM preform to a sufficient amount to create a product having an internal passage therein, wherein the product is configured with wrought properties for that material via the deforming step.

Abstract: Methods for creating three-dimensional volume quality models of additively manufactured metal bodies are disclosed. In one embodiment, a method comprises additively manufacturing each metal layer of a metal body. One or more images of the first metal layer are obtained. The image(s) are processed to detect and map potential manufacturing defects in the first metal layer. A two-dimensional contour of the first metal layer is generated from the three-dimensional CAD model. The mapped defects are integrated into the two-dimensional contour. A first layer of a three-dimensional volume quality model of the metal body is created based on the integrated two-dimensional contour.

Abstract: An apparatus and method for separating welded multi-layered samples has a slotted engine-driven spindle that twists and pulls a layer from the sample, breaking the welds as the layer winds around the spindle. The sample is held between two clamps and a tensioning cylinder pulls a movable first clamp against the second stationery clamp. Sensors may sense the force required to break the welds and the data may be stored and analyzed in a computer.

Abstract: A tie down assembly adapted to be installed within a structure includes a cup and a crossbar that is fastened removably to the cup by a plurality of fasteners. The cup includes a recess forming an interior surface, and a plurality of seats extending from the interior surface. The crossbar includes a central portion and a plurality of elongated members extending therefrom. Each of the members includes a head that engages a corresponding one of the seats of the cup and is secured to the seat by one of the fasteners. The central portion of the crossbar may include a central aperture that receives one of the fasteners for an additional attachment point to the cup. The crossbar is adapted to receive tie down hooks, connectors, and the like. When the crossbar requires repair or replacement, it may be removed from the cup by unfastening the fasteners without the need to remove the cup from the structure.

Abstract: A tie down assembly adapted to be installed within a structure includes a cup and a plate fastened removably to the cup by fasteners. The cup includes a first sidewall, an interior portion, and a plurality of seats that extends within the interior portion. The plate an aperture to receive tie down connectors. The plate includes a plurality of tabs. The plate is positioned within the interior portion of the cup and rests on the seats. When the plate requires repair or replacement, it may be removed from the cup by unfastening the fasteners without the need to remove the cup from the structure. Each of the tabs of the plate is positioned within a space between adjacent pairs of the seats of the cup and is adapted to engage the seats of the cup so as to inhibit rotation of the plate relative to the cup.

Abstract: A tie down assembly including a cup, a cross-shaped crossbar that is fastened removably to and positioned within a recess of the cup, and a disc-shaped plate that is fastened removably to the cup and/or the crossbar. The crossbar is fastened to the cup by a plurality of fasteners, while the plate is fastened to the cup and/or the crossbar by at least one fastener. The cup is installed within a hole formed within a first surface of a structure, and the plate is positioned against an opposite surface of the structure. When the plate is attached, a compressive load is introduced and squeezes the first and second surfaces of the structure together, such that most of the load is borne down the center of the fastener attaching the plate.
