ABSTRACT:
A railroad wheel formed from at least two metallic alloys. In one embodiment, a railroad wheel has a body formed from a first alloy and a rim formed from a second alloy initially in powder form. In an exemplary embodiment, to form the dual alloy wheel the body of the wheel is cast with a circumferential channel formed therein. The perimeter of the body is enveloped with a material, such as sheet metal, to form a cavity defined by the channel and the sheet metal. The second alloy in the form of a powder is placed in the cavity and subjected to heat and pressure to metallurgically weld the first and second alloys and form a composite railroad wheel.
