Abstract: A process for additive manufacturing of a metal alloy material is provided that includes: a) providing a feedstock powder comprising base powder particles with nanoparticles attached to surfaces of the base powder particles; b) providing an additive manufacturing system with a laser power source relatively movable at a scan speed; c) wherein the additive manufacturing system has a process window for the feedstock powder; and d) exposing the feedstock powder to a predetermined power input from the laser power source at a predetermined scan speed to produce the metal alloy material. The concentration by volume of nanoparticles within the feedstock powder is such that independent first and second microstructures may be produced within the metal alloy material.

Abstract: A cost-effective method of forming a hydrophobic coating on a substrate and coated substrates are disclosed. Specifically, the method comprises applying amorphous powders of an alloy to the substrate through a cold spray process. Also provided is a novel type of hydrophobic coating made of metallic glasses or amorphous alloys. The hydrophobic coatings offer advantages such as, low cost, low maintenance, and high corrosion resistance.

Abstract: A method for fabricating a ceramic material includes impregnating a porous structure with a mixture that includes a preceramic polymer and a filler. The filler includes at least one free metal. The preceramic polymer material is then rigidized to form a green body. The green body is then thermally treated to convert the rigidized preceramic polymer material into a ceramic matrix located within pores of the porous structure. The same thermal treatment or a second, further thermal treatment is used to cause the at least one free metal to move to internal porosity defined by the ceramic matrix or pores of the porous structure.

Abstract: A system for direct writing a conformal or free-form magnet includes producing a magnetic ink compound by mixing an photopolymer base and a magnetic material powder, extruding a layer of the magnetic ink compound through a nozzle on to a target substrate to form a layer, soft-curing the layer by exposing the layer to a first light, repeatedly extruding a layer and soft-curing the layer, then post-curing the magnet by exposing the magnet to a second light and an elevated temperature.

Abstract: Methods for fabricating a ceramic matrix composite are disclosed. A fiber preform may be placed in a mold. An aqueous solution may be added to the fiber preform. The aqueous solution may include water, carbon nanotubes, and a binder. The preform may be frozen. Freezing the preform may cause the water to expand and separate fibers in the fiber preform. The carbon nanotubes may bond to the fibers. The preform may be freeze dried to remove the water. The preform may then be processed according to standard CMC process.
