    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.

    Abstract: Provided are a low emissivity film and a window having the same. According to an embodiment of the inventive concept, the low emissivity film may include a first substrate, a first metal oxide layer, a first reflective layer, a second metal oxide layer, and a second substrate. The first metal oxide layer may reflect light having a wavelength of infrared rays. The light having a first wavelength is reflected by cavity effect of the first metal oxide layer, the first reflective layer, and the second metal oxide layer, and the light having a second wavelength may pass through the low emissivity film. Thus, the low emissivity film may express a color.

    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.
