摘要： An aluminum alloy that can be cast into structural components wherein at least some of the raw materials used to produce the alloy are sourced from secondary production sources. In addition to aluminum as the primary constituent, such an alloy includes 5 to 14% silicon, 0 to 1.5% copper, 0.2 to 0.55% magnesium, 0.2 to 1.2% iron, 0.1 to 0.6% manganese, 0 to 0.5% nickel, 0 to 0.8% zinc, 0 to 0.2% of other trace elements selected from the group consisting essentially of titanium, zirconium, vanadium, molybdenum and cobalt. In a preferred form, most of the aluminum is from a secondary production source. Methods of analyzing a secondary production aluminum alloy to determine its constituent makeup is also disclosed, as is a method of adjusting the constituent makeup of such an alloy in situations where the alloy is out of tolerance when measured against its primary source counterpart.

摘要： A computer-implemented system and method of rapidly predicting at least one of residual stress and distortion of a quenched aluminum casting. Input data corresponding to at least one of topological features, geometrical features and quenching process parameters associated with the casting is operated upon by the computer that is configured as a neural network to determine output data corresponding to at least one of the residual stress and distortion based on the input data. The neural network is trained to determine the validity of at least one of the input data and output data and to retrain the network when an error threshold is exceeded. Thereby, residual stresses and distortion in the quenched aluminum castings can be predicted using the embodiments in a tiny fraction of the time required by conventional finite-element based approaches.

摘要： Integrated devices and methods for compensating electric grade steel lamination stack height for use in a conventional two-plate high pressure die cast tool used for casting aluminum induction rotors. These devices and methods allow for significant variation in the lamination stack height without associated failures related to stack height variation, and also ensure constant and accurate clamping pressure on both the OD and ID of the steel lamination stack which prevents electric insulation damage, metal flow between laminations, large casting metal flash, and tool damage for excessive height laminations stacks. The clamping pressure is adjustable and is actuated from a single hydraulic cylinder which allows for a wide range of pressures to accommodate fine adjustment of clamping pressure to insure no damage occurs to the laminations.

摘要： A quantitative metallographic method to measure skin layer thickness in high pressure die cast aluminum components. Because the faster-cooling skin layer region exhibits a higher volume fraction of eutectic phases than that of a slower-cooling inner region, measurements showing such higher eutectic phases can be used to quantify such layer thickness. An image at various thicknesses of a location of interest in a cast component sample is first obtained using an image analyzer, from which eutectic volume fractions within each of the received images may be determined. Comparisons of the determined volume fractions can be made against a known or predicted quantity for a particular alloy composition, and then correlated to the skin layer thickness via differences between the received or measured quantities and those of the known standard.

摘要： A method of reducing entrained aluminum oxides in aluminum castings. The method comprises preheating a furnace charge to remove moisture and contaminants. The furnace charge is then coated on all free surfaces with a layer of flux. Subsequently the furnace charge is melted in a furnace to form a melt bath of liquid aluminum suitable for casting. The flux layer removes the naturally occurring oxide film from the furnace charge surface as well as provides a cover flux to protect the melt bath from oxidation.
