Abstract: Morphology, microstructure, compressive behavior, and biocorrosive properties of magnesium or magnesium alloy foams allow for their use in biodegradable biomedical, metal-air battery electrode, hydrogen storage, and lightweight transportation applications. Magnesium or Mg alloy foams are usually very difficult to manufacture due to the strong oxidation layer around the metallic particles; however, in this invention, they can be synthesized via a camphene-based freeze-casting process with the addition of graphite powder using precisely controlled heat-treatment parameters. The average porosity ranges from 45 to 85 percent and the median pore diameter is about a few tens to hundreds of microns, which are suitable for bio and energy applications utilizing their enhanced surface area. This invention based on powder-slurry freeze-casting method using camphene as a volatile solvent is also applicable for other metal foams such as iron, copper, or others to produce three-dimensional metal foams with high strut connectivity.

Abstract: A mixed silver powder and a conductive paste comprising the powder are disclosed. The mixed silver powder is obtained by mixing two or more spherical silver powders having different properties from each other. The mixed powder may minimize the disadvantages of the respective types of the two or more powders and maximize the advantages thereof, thereby improving the characteristics of products. In addition, by comprehensively controlling the particle size distribution of surface-treated mixed silver powder and the particle diameter and specific gravity of primary particles, a high-density conductor pattern, a precise line pattern, and the suppression of aggregation over time can be simultaneously achieved.

Abstract: This disclosure provides an improvement over the state of the art by teaching a low-cost method to produce feedstock powder, without undergoing a phase change, from industrially relevant wrought alloys that are widely available at low cost. The surfaces of aspherical particles are functionalized with particulates having a different size and composition than the particles, to control the solidification response of the feedstock. Some variations provide a metal-containing functionalized material comprising: a plurality of aspherical particles comprising a metal or a metal alloy; and a plurality of metal-containing or ceramic particulates that are assembled on surfaces of the aspherical particles, wherein the particulates are compositionally different than the aspherical particles. Methods of making and using the metal-containing functionalized materials are described. The invention provides an economic advantage over traditional gas-atomized or water-atomized metal powder feedstocks for powder-based metal additive manufacturing or other powder metallurgy processes.
