A process manufactures a metal part for a turbomachine that includes first and second metal materials with different chemical compositions. The process includes the steps of obtaining an element of which at least a first metallic part is made of the first metallic material and placing the element in a first mold and pouring wax into the mold to at least partially cover the element. The first mold has an impression corresponding to at least part of an external surface of the metal part. The process further includes obtaining an assembly by removing the first mold and making a shell mold with a first ceramic around the assembly. The process also includes removing the wax from the shell mold and pouring the second metal material into the shell mold in place of the wax, and removing any ceramics present in the assembly.
