Abstract (en)
A steel shaft is disposed in a forging metallic die, and aluminum alloy powder or its preliminarily formed body is charged in the metallic die around the steel shaft. The aluminum alloy powder or its preliminarily formed body is forged so that a rotor of aluminum powder alloy is manufactured, and at the same time, the rotor is connected and fixed to the shaft. <IMAGE>
