    Abstract: A method of manufacturing a crystalline aluminum-iron-silicon alloy and a crystalline aluminum-iron-silicon alloy part. An aluminum-, iron-, and silicon-containing composite powder is provided that includes an amorphous phase and a first crystalline phase having a hexagonal crystal structure at ambient temperature. The composite powder is heated at a temperature in the range of 850° C. to 950° C. to transform at least a portion of the amorphous phase into the first crystalline phase and to transform the composite powder into a crystalline aluminum-iron-silicon (Al—Fe—Si) alloy. The first crystalline phase is a predominant phase in the crystalline Al—Fe—Si alloy.

    Abstract: Methods of making high-strength, lightweight alloy components capable of high temperature performance comprising aluminum, silicon, and iron and/or nickel are provided. A high-energy stream, such as a laser or electron beam, may be selectively directed towards a precursor material to melt a portion of the precursor material in a localized region. The molten precursor material is cooled at a rate of greater than or equal to about 1.0×105 K/second to form a solid high-strength, lightweight alloy component comprising a stable ternary cubic phase having high heat resistance and high strength. The stable ternary phase may be AlxFeySiz, where x ranges from about 4 to about 5 or about 7.2 to about 7.6, y is about 1.5 to about 2.2, and z is about 1. The stable ternary phase may also be Al6Ni3Si. Materials and components, such as automotive components, made from such methods are also provided.

    Abstract: A positive electrode includes a lithium-based active material, a binder, a conductive filler, and discrete aluminum oxide nanomaterials. The aluminum oxide nanomaterials are mixed, as an additive, throughout the positive electrode with the lithium-based active material, the binder, and the conductive filler. The positive electrode with the discrete aluminum oxide nanomaterials may be incorporated into a lithium ion battery. The aluminum oxide nanomaterials may be formed by the following method. A solution is formed by mixing an aluminum oxide precursor and an acid. A carbon material is added to the solution, thereby forming an aqueous mixture having the carbon material therein. Hydrothermal synthesis is performed using the aqueous mixture, and precursor nanostructures are grown on the carbon material. The precursor nanostructures on the carbon material are annealed so that the carbon material is removed and aluminum oxide nanomaterials are formed.
