dc.description.abstract |
The operational degradation of surface layers due to a rolling contact process was simulated for Hadfield steel by a special testing rig. A specific limited state based on cumulative depletion of plasticity was achieved. Precise evaluation of the surface layer's mechanical parameters is necessary for a service life prediction. Very low depth of localized dislocation hardening process doesn´t allow the standard mechanical testing. The comparative instrumented indentation tests using Vickers and cylindrical indenter were used for evaluation of defined stage of surface degradation process. The intensity and reach of deformation hardening are partially limiting for particular methodology. The yield stress of surface layers was estimated according to an analytical model of uniaxial vs. indentation plastic flow ratio. |

Provozní degradace povrchových vrstev Hadfieldovy oceli byla simulována pomocí specielního standu; dosažen byl specifický mezní stav kumulativního vyčerpání plasticity. Pro hodnocení definovaného stadia degradačního procesu v povrchové vrstvě oceli byly použity porovnávací indentační testy použitím Vickersova a válcového indentoru. Mez kluzu povrchových vrstev byly stanovena použitím analytického modelu pro posouzení plastického toku indentace. |
