A method for fabricating an article that includes: providing a first workpiece component formed of a first steel material; joining a second workpiece component to the first workpiece component to form a workpiece, the second workpiece component being formed of a second steel material that is different from the first steel material; and forming a plurality of teeth on the workpiece, the teeth being wholly formed of the first steel material.

A carrier and at least one pin shaft of a gearbox of a wind turbine and method of manufacturing same includes forming the carrier and the pin shaft(s) as a single part or separate components. Further, the method includes forming one or more voids in the pin shaft(s) and/or the carrier via additive manufacturing. As such, the void(s) is configured to increase flexibility of the pin shaft(s)/carrier so as to improve a load distribution thereof.

A method for producing and processing a cylindrical hollow body (20) made of aluminum or an aluminum alloy and for arranging cylindrical hollow body (20) in a motor vehicle transmission includes producing the hollow body (20) by a casting process (1) in such a way that the hollow body (20) has an inner and an outer lateral surface (21, 22) and has internal toothing (24) on the inner lateral surface (21), and centrally clamping the hollow body (20) for processing. The hollow body (20) is arranged in the vehicle transmission exclusively via tooth flanks of the internal toothing (24) (6). The hollow body (20) is clamped centrally (2) exclusively on a partial region (23) of the inner lateral surface (21), away from the internal toothing (24).
