Abstract

In a process for tempering at least parts of a wheel for rail vehicles, the tempering temperature is kept at least approximately constant or intermittently altered in the range of the temperature/time curves for the beginning and end of austenitic conversion. This provides a rail vehicle wheel with improved high-speed behaviour.
