  • Patent number: 10604826
    Abstract: Aluminum and aluminum alloy microstructures that are adapted for improved performance during shaping and forming production processes. Lower relative ratios of alpha fibers, particularly low-end alpha fibers, to beta fibers promotes improved formability of aluminum sheet or blanks without negatively impacting material strength. Beta fibers with higher relative ratios of S and Copper texture components improve formability and produce fewer and more uniform distortions during production. The resulting improvements in quality allow for cupping, drawing, wall ironing, shaping, and necking processes to be carried out faster and with reduced rates of spoilage.

  • Patent number: 9064852
    Abstract: A thermally conductive composite material, a thermal transfer device made of the material, and a method for making the material are disclosed. Apertures or depressions are formed in aluminum or aluminum alloy. Plugs are formed of thermal pyrolytic graphite. An amount of silicon sufficient for liquid interface diffusion bonding is applied, for example by vapor deposition or use of aluminum silicon alloy foil. The plugs are inserted in the apertures or depressions. Bonding energy is applied, for example by applying pressure and heat using a hot isostatic press. The thermal pyrolytic graphite, aluminum or aluminum alloy and silicon form a eutectic alloy. As a result, the plugs are bonded into the apertures or depressions. The composite material can be machined to produce finished devices such as the thermal transfer device. Thermally conductive planes of the thermal pyrolytic graphite plugs may be aligned in parallel to present a thermal conduction path.

  • Publication number: 20150083280
    Abstract: A shaped metal casting made in an aggregate mold comprises fine solidification microstructure that is finer than the solidification microstructure of an analogous metal casting made from conventional molding processes. The solidification microstructure may be up to five times finer than the solidification microstructure of a conventionally prepared casting. In preferred embodiments, as a result of directional solidification, the fine solidification microstructure is substantially continuous from a distal end of the casting to a proximal end of the casting, and exhibits greatly enhanced soundness. Because of the control of the uniformity of freezing of the casting, its properties are substantially uniform.
