Abstract: Some variations provide an additively manufactured metal-containing component comprising (i) nickel, (ii) aluminum and/or titanium, and (iii) nanoparticles, wherein the sum of aluminum weight percentage and one-half of titanium weight percentage is at least 3 on a nanoparticle-free basis, and wherein the additively manufactured metal-containing component has a microstructure that is substantially crack-free with equiaxed grains. A feedstock composition is also provided, comprising metal-containing microparticles and nanoparticles, wherein the nanoparticles are chemically and/or physically disposed on surfaces of the microparticles, wherein the microparticles comprise (i) nickel and (ii) aluminum and/or titanium, and wherein the sum of aluminum weight percentage and one-half of titanium weight percentage is at least 3 on a nanoparticle-free basis. The nanoparticles may be selected from metals; ceramics; cermets; intermetallic alloys; oxides, carbides, nitrides, borides, or hydrides thereof; polymers; and/or carbon. Successful nanofunctionalization of MAR-M-247 nickel superalloy is demonstrated, creating a crack-free additively manufactured microstructure.

Abstract: Some variations provide a functionalized composite material comprising: a thermoplastic polymer binder matrix disposed in a distinct volume; a plurality of discrete metal or metal alloy particles dispersed in the thermoplastic polymer matrix; and a plurality of discrete particulates assembled on surfaces of the discrete metal or metal alloy particles, wherein the discrete particulates are in contact with the thermoplastic polymer binder matrix, wherein the discrete particulates are smaller than the discrete metal or metal alloy particles in at least one dimension, and wherein the discrete particulates are compositionally different than the discrete metal or metal alloy particles. The discrete particulates may be selected and/or configured to function as a grain refiner, a sintering aid, and/or a strengthening phase, within the functionalized composite material.

Abstract: A wire explosion assembly configured to form nanoparticles by exploding at least a segment of an electrically conductive wire. The wire explosion assembly includes a spool supporting the electrically conductive wire, a vessel defining a wire explosion chamber, means in the wire explosion chamber for pulling the electrically conductive wire off of the spool and applying tension on the segment of the electrically conductive wire, and a power source for delivering an electrical current to the segment of the electrically conductive wire. The electrical current is configured to explode the segment of the electrically conductive wire into the nanoparticles.

Abstract: A method of manufacturing a heat exchanger including a heat exchanger core of a first material, the method including additive manufacturing a sacrificial scaffold of a second material, the sacrificial scaffold corresponding in shape to that of the heat exchanger core, coating the sacrificial scaffold with a layer of the first material, and removing the sacrificial scaffold to leave behind the heat exchanger core with an integrated self-aligned passage.
