ABSTRACT:
A method for connecting a wheel, such as a turbine wheel or compressor wheel, in a turbine wheel rotor. The method includes providing a shaft made of steel, and pouring a casting alloy around an end of the shaft, wherein the casting alloy includes an intermetallic compound of the system TiAl. The method is particularly well-suited making a connection of the turbine wheel and the shaft of an exhaust-gas turbocharger for motor vehicles using a casting process. In addition, a turbine wheel rotor, that includes a steel shaft, a cast wheel including a casting alloy fixedly connected to an end of the shaft. The casting alloy including an intermetallic compound of the system TiAl. A connection between the cast wheel and the shaft includes at least one of a friction fit, a positive fit, and an integral connection.
