摘要： A system may include a current source; a first metal or alloy component with a first major surface electrically coupled to the current source; a second metal or alloy component with a second major surface electrically coupled in series to the first component and the current source via an external electrical conductor, where the first and second major surfaces are positioned adjacent to each other to define a joint region; a metal or alloy powder disposed in at least a portion of the joint region; and a controller. The controller may be configured to cause the current source to output an alternating current that conducts through the first component and the second component to induce magnetic eddy currents, magnetic hysteresis, or both within at least a portion of the metal or alloy powder disposed in at least the first portion of the joint region.

摘要： A method may include fused filament fabricating a fused filament fabricated component by delivering a softened filament to selected locations at or adjacent to a build surface. The softened filament may include a sacrificial binder and a powder including a shape memory alloy (SMA). The method also may include removing substantially all the sacrificial binder from the fused filament fabricated component to leave an unsintered component; and sintering the unsintered component to join particles of the SMA and form an SMA component.

摘要： A method may include cold spraying a masking material on selected locations of a component to form a masking layer, wherein the masking material comprises a metal or alloy; additively manufacturing an additively manufactured portion of the component at locations at which the masking layer is not present; and removing the masking layer from the component. The masking layer may be configured to protect portions of the component by covering or otherwise providing a physical barrier that reduces or prevents material from adhering to unwanted portions of the component during a subsequent manufacturing and/or repair technique. Additionally, the masking layer may be reflective to infrared radiation and/or intimately contact the component and function as a heat sink or thermally conductive layer to transfer heat from the component.

摘要： An example technique may include depositing, on or adjacent a substrate, a first volume of a polymeric material using an additive manufacturing technique. The first volume of the polymeric material has a first degree of polymer orientation associated with a first deposition rate and a first temperature. The example technique may include depositing, on or adjacent the substrate or the first volume of material, at least one second volume of the polymeric material. The second volume of the polymeric material has a second degree of polymer orientation associated with a second deposition rate and a second temperature. The first volume and the second volume are configured to respond to a shape change stimulus by exhibiting a respective first change in dimension and a second change in dimension. The first change in dimension is different from the second change in dimension by a predetermined threshold.
