A rotor shaft assembly ( 101 ) of a type used in a turbocharger, manufactured by mounting a powder compact of a titanium aluminide rotor ( 203 ) to a powder compact of a steel shaft ( 207 ), with a metal powder admixed with a binder ( 211 ) interposed between the rotor and shaft, and debinding and sintering the mounted compact combination. Sintering produces a strong metallurgical bond between the shaft and rotor, providing a near-net rotor shaft assembly ( 101 ) and also an inexpensive and efficient method for the manufacture of an assembly capable of withstanding the high forces and temperatures within a turbocharger.
