Abstract:
A method is provided for producing a wrought aluminum eutectic composite characterized by improved physical properties. The method resides in forming a casting of an aluminum alloy characterized metallographically by the presence of a eutectic structure, and then heat treating the casting at a temperature related to the eutectic-forming temperature of said alloy casting, that is just below its incipient melting point. The heat treatment is continued for a time at least sufficient to convert the morphology of the eutectic to dispersed fine particles of reinforcing phase(s), following which the alloy is physically worked to reduce the cross section thereof and provide a wrought aluminum eutectic composite characterized by improved physical properties.
