    Abstract: 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.

    Abstract: 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.

    Abstract: An induction rotor assembly having conductive bars is provided. The assembly comprises a lamination stack comprising a body having a first end and second ends to define a longitudinal axis. The body has an outer circumferential portion extending from the first end to the second end. The outer portion has a plurality of walls defining open slots formed from the first end through the second end. The assembly further comprises a first ring disposed on the first end and a second ring disposed on the second end. The assembly further comprises a plurality of conductive bars extending between the first and second rings. Each conductive bar is disposed in one of the slots such that the respective conductive bar is in contact with the lamination stack and connects the first and second rings. Each bar comprises an inner portion and a conductive outer skin disposed about the inner portion.
