A rotor shaft assembly ( 101 ) of a type used in a turbocharger, manufactured by mounting a powder compact ( 203 ) of a titanium aluminide rotor ( 103 ) to a pre-formed steel shaft ( 107 ), and sintering the combination, which provides a strong metallurgical bond between the shaft ( 107 ) and rotor ( 103 ). There is provided a rotor shaft assembly ( 101 ) and an inexpensive and efficient method of its manufacture, for an assembly capable of withstanding the high forces and fluctuating temperatures within a turbocharger.
