Original abstract

Fatigue behaviour of UFG Cu of high and low purity produced by means of ECAP and using different ECAP routes was studied. S/N curves and cyclic hardening/softening curves were experimentally determined. It has been found that both the purity and ECAP path influence the fatigue lifetime and cyclic plasticity in high cycle fatigue region. The mechanism of fatigue damage of UFG structure has been discussed.

Czech abstract

V práci byla provedena studie únavového chování UFG Cu nízké a vysoké čistoty produkované pomocí ECAP techniky a užití různých způsobů ECAP procesu. Experimentálně byly určeny S-N křivky a křivky zpevnění/změkčení UFG Cu. V oblasti vysokocyklové únavy byl zjištěn výrazný vliv způsobu ECAP procesu a čistoty na životnost UFG Cu. Byl diskutován mechanismus únavového porušování UFG struktury.
