摘要： We have developed a scalable approach to directly incorporate grain-refining nanoparticles into conventional hot-tear-susceptible aluminum alloy powders. These aluminum alloy powders may be additively manufactured into high-strength, crack-free aluminum alloys with fine equiaxed microstructures by incorporating nanoparticle nucleants to control solidification during additive manufacturing. Some variations provide an additively manufactured aluminum alloy comprising aluminum, one or more strengthening elements, and at least one grain-refining element, wherein the additively manufactured aluminum alloy has a microstructure with equiaxed grains. Aluminum alloys with grain refiners are useful in many processes beyond additive manufacturing. Some variations provide an aluminum alloy comprising aluminum, copper, magnesium, at least one of zinc or silicon, and grain-refining nanoparticles selected from zirconium, tantalum, niobium, or titanium, wherein the aluminum alloy has a microstructure that is substantially crack-free with equiaxed grains.

摘要： Some variations provide a method of making an additively manufactured metal component, comprising: providing a feedstock that includes a high-vapor-pressure metal; exposing a first amount of the feedstock to an energy source for melting; and solidifying the melt layer, thereby generating a solid layer of an additively manufactured metal component. The metal-containing feedstock is enriched with a higher concentration of the high-vapor-pressure metal compared to its concentration in the additively manufactured metal component. The high-vapor-pressure metal may be selected from Mg, Zn, Li, Al, Cd, Hg, K, Na, Rb, Cs, Mn, Be, Ca, Sr, or Ba, for example. Additively manufactured metal components are provided. Metal-containing feedstocks for additive manufacturing are also disclosed, wherein concentration of at least one high-vapor-pressure metal in the feedstock is selected based on a desired concentration of the high-vapor-pressure metal in an additively manufactured metal component derived from the metal-containing feedstock. Various feedstock compositions are disclosed.

摘要： This invention describes spherical nanoparticle hydrides and a method for making them. A method of producing spherical nanoparticle hydrides comprises obtaining an electrically conductive or semiconductive wire fabricated from a base material capable of forming a hydride; exposing the wire to a hydrogen-containing processing gas under pressure; vaporizing the wire by electrical discharge, to generate a vapor phase; and reacting with hydrogen and condensing the vapor phase, generating a plurality of spherical nanoparticle hydrides. A composition of spherical nanoparticles is also provided, wherein each of the nanoparticles contains a base material that is electrically conductive or semiconductive and capable of forming a hydride, and hydrogen that is chemically or physically bonded with the base material, wherein the nanoparticles are characterized by a number-average particle diameter from 1 nanometer to 1000 nanometers, and wherein the nanoparticles are characterized by an average hydrogen content from 10 atom % to 85 atom %.
