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: A device and article of manufacture to predict material properties of a cast aluminum-based component. In one form, a computer-based system includes numerous computation modules programmably cooperative with one another such that upon receipt of data that corresponds to the cast aluminum-based component, the modules provide performance indicia of the material. The modules include a thermodynamic calculation module, a thermal-physical property module, a mechanical property module and a materials selection or alloy design module. The combination of the modules along with known material and geometric databases—in addition to microstructural and defect databases—promotes the generation of materials properties needed for casting design, casting process simulation, CAE nodal property mapping and durability analysis.

Abstract: A quantitative metallographic method to measure pore sizes and pore distributions in cast aluminum components. An image of a location of interest in a cast component sample is first obtained using an image analyzer. Spacing criteria, such as a measure of the secondary dendrite arm spacing, may be used with the received image to provide evidence of pore clustering. This allows the system to performing calculations to determine if multiple pores can be clustered or grouped together as a single pore in three-dimensional space. From this, the total area of the pores in each of these groups or clusters is calculated and used as a representation of the pore area for that cluster. In general, pore size and pore distribution measurements in cast components achieved by the present invention show accurate predictions of pore size and spacing, and in particular evidence a reduced tendency to under-predict the size and distribution of actual pores.
Abstract translation: 用于测量铸铝组分中的孔径和孔分布的定量金相法。 首先使用图像分析仪获得投射成分样本中感兴趣的位置的图像。 间隔标准，例如二次枝晶臂间距的测量，可以与接收的图像一起使用以提供孔聚集的证据。 这允许系统执行计算以确定多孔是否可以聚集或组合在一起作为三维空间中的单个孔。 由此，计算每个这些组或簇中的孔的总面积，并将其用作该簇的孔面积的表示。 通常，通过本发明实现的铸造组分中的孔径和孔分布测量显示了孔径和间距的准确预测，并且特别地证明了预测实际孔的尺寸和分布的降低的倾向。
