Abstract
Official abstract text for this publication.
A method of forming a bimetallic forging includes providing a blank comprising at least a first element and a second element of a first metal, and an insert of a second metal. A blank is configured such that the insert may be substantially encapsulated by a shell defined by the first element and the second element. The blank is forged to form a bimetallic forging including an outer portion defined by the shell, an inner portion defined by the insert, and an interface layer therebetween. In a non-limiting example, the first metal is substantially comprised of aluminum and the second metal is substantially comprised of magnesium. In a non-limiting example, the blank may be forged to form a vehicle wheel including an aluminum skin substantially encapsulating a magnesium inner portion, providing wheel with a high strength to weight ratio and improved corrosion performance.
