Zusammenfassung:	Methods are provided for manufacturing a component. In one method, first metal material is cast into a first body. At least a portion of the first body is machined. Second metal material is cast onto at least the machined portion of the first body to form a monolithic second body. A first portion of the second body is formed by the first metal material, A second portion of the second body is formed by the second metal material. The second metal material is different from the first metal material.
