Abstract: A component includes a dense base region, a dense replacement region and an additively manufactured (AM) porous region between the dense base region and the dense replacement region. The porous region has a porosity between 2% to 50% open space volume to total volume of the AM porous region. The porous region can be printed onto the base region or the replacement region. A braze material couples the base region, the porous region and the replacement region together, and infiltrates into the porous region based at least on a characteristic of the porosity. The porous region reduces stress at a joint between the dense regions and can be customized to create different physical characteristic(s) than just those of the base and replacement regions.

Abstract: A component includes a body having a coupon opening defined therein, and an additively manufactured (AM) metal coupon including a dense region, a porous region adjacent the dense region, and a coupon outer surface. The porous region has a first cross-sectional area at a first location at or near the coupon outer surface and a second cross-sectional area less than the first cross-sectional area at a second location distal from the coupon outer surface. A braze material couples the metal coupon in the coupon opening and infiltrates into the porous region, e.g., based at least on a characteristic of the porosity thereof. The dense region may have a third cross-sectional area at the first location and a fourth cross-sectional area greater than the third cross-sectional area at the second location so it can direct the braze material in the porous region toward an inner surface of the coupon opening.

Abstract: A component includes a body and an additively manufactured (AM) metal coupon that includes at least one first porous region having a first porosity and may include any number of second porous regions having a second porosity different than the first porosity. A braze material couples the metal coupon in a coupon opening in the body. The braze material infiltrates into at least one of the first porous region based at least on a characteristic of the first porosity or any second porous region based at least on a characteristic of the second porosity. The different porosities can be customized to provide the first porous region and the second porous region with the braze material therein with different physical characteristic(s).

Abstract: A component including a body, and an additively manufactured (AM) metal coupon including a first section and a stress-relief section, is disclosed. The stress-relief section includes a porous region having a porosity between 2% to 50% open space volume to total volume of the stress-relief section. The stress-relief section has at least one of thermal conductivity, tensile strength, ductility, or fatigue strength less than first section. A braze material couples the AM metal coupon to a coupon opening in the body. The stress-relief section creates a low-stress zone in the metal coupon that can be located near or adjacent to a high-stress zone. The stress-relief section reduces residual stress in the metal coupon, which reduces the related challenges of coupling the metal coupon to the body of the component, especially where superalloy materials are used.

A second porous region may be provided inside the conduit to increase heat rejection of the conduit.

Abstract: A component includes a body and an additively manufactured (AM) metal coupon that includes a primary member having a member porosity between 2% to 50% open space volume to total volume of the primary member. The primary member includes a first portion and a second portion distanced from the first portion by a gap. At least one thermal transfer structure, such as pin(s) and/or fin(s), extends between the first and second portions across the gap. A braze material couples the AM metal coupon in a coupon opening in the body, and infiltrates into the primary member based at least on a characteristic of the member porosity. The braze material may also infiltrate the thermal transfer structure(s), which may have the same or different porosity from the primary member. The thermal transfer structure(s) exhibit enhanced heat rejection, reduce weight of the component, and may improve component vibratory response.

Abstract: A metal coupon for repairing a component includes an additively manufactured (AM) metal member having a sealed cavity in an interior of the AM metal member, and a porous region around the sealed cavity. A metal coupon system may include at least two AM metal parts with each AM metal part including at least a section of a sealed cavity therein and a porous region around the at least section of the sealed cavity. The AM metal parts combine to form the metal coupon, i.e., AM metal member, with the sealed cavity in an interior thereof and the porous region around the sealed cavity. In any event, the sealed cavity is hollow. The metal coupon with the sealed cavity provides reduced mass and allows braze material to be directed based on characteristics of the porous region of the metal coupon.

Abstract: A metal coupon for repairing a component includes an additively manufactured (AM) metal member having at least two porous regions and a braze material infiltration barrier positioned between the at least two porous regions. The braze material infiltration barrier has a lower porosity than the at least two porous regions. A component using the metal coupon may also include a braze material coupling the metal coupon in a coupon opening in the body. The braze material infiltrates at least one of the two porous regions, and the braze material infiltration barrier separates the braze material in the at least one of the two porous regions from at least one other of the at least two porous regions. Different braze materials may be used in each porous region.

Abstract: A metal coupon for repairing a component includes an additively manufactured (AM) metal member having a low porosity region in an interior of the AM metal member, and a porous region around the low porosity region.

The porous metal coupon with low porosity region allows braze material to be directed based on characteristics of the porous region.

The braze material infiltrates into the porous region.
