Abstract
A process or an arrangement for the increase of alternating torsion stress of a component (23) provided with a groove (22) provides for a hardening of only the groove bottom edge areas (20, 21) by at least one energy-rich beam (24, 25), whereby inert gas is introduced into the groove (22) (Figure 2) by means a nozzle (28) in order to avoid surface changes in the component (23).
