    Abstract: Aluminum alloys having improved properties are provided. The alloy includes about 13 to about 17 weight percent silicon, about 0.3 to about 0.6 weight percent magnesium, and at least 75 weight percent aluminum. The alloy may include copper up to about 2.0 weight percent; iron up to about 0.8 weight percent; manganese up to about 1.0 weight percent; nickel up to about 1.0 weight percent; zinc up to about 0.8 weight percent; titanium up to about 0.5 weight percent; zirconium up to about 0.5 weight percent; vanadium up to about 0.5 weight percent; and other trace elements up to about 0.1 weight percent. In addition, the alloy may contain about 50 to about 1000 ppm of strontium and about 10 about 100 ppm phosphorus. Also disclosed is a die cast article, such as transmission clutch housing.

    Abstract: A method of eliminating microstructure inheritance of hypereutectic aluminum-silicon alloys. The method includes heating a first amount of the Al—Si alloy to a predetermined temperature above a liquidus temperature of the Al—Si alloy to form a first amount melt; holding the first amount melt at the predetermined temperature for a predetermined amount of time; stirring the first amount melt during the predetermined amount of time; heating a second amount of the Al—Si alloy above the liquidus temperature of the Al—Si alloy to form a second amount melt; and mixing the first amount melt and the second amount melt to form a processed Al—Si casting alloy. The predetermined temperature is between about 750° C. to 850° C. The predetermined amount of time is between 0.1 hour to 0.5 hour. The processed Al—Si casting alloy contains about 30 wt % to about 40 wt % of the first amount of the Al—Si alloy.

    Abstract: A method of forming a bi-metallic casting. The method includes providing a metal preform of a desired base shape defining a substrate surface and removing a natural oxide layer and surface contamination from the substrate surface to yield a cleaned metal preform. The method further includes galvanizing the cleaned metal preform, yielding a galvanized metal preform followed by electroplating a thin nickel film on at least a portion of the substrate surface of the galvanized metal preform. Additionally, the method includes metallurgically bonding the portion of the metal preform having the nickel film with an overcast metal to form a bi-metallic casting. The nickel film promotes a metallurgical bond between the metal preform and the overcast metal.
