The results revealed that the creep behaviour of pressed material strongly depends on the number of ECAP passes The ECAP material exhibits the highest creep resistance after the first ECAP pass However, successive ECAP passes lead to a noticeable decrease in the creep properties of the pressed copper The results indicate conventional power-law creep with a stress exponent of similar to`5 - 6 which is consistent with an intragranular dislocation process involving the glide and climb of dislocations Pracoviště Ústav fyziky materiálu Kontakt Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Rok sběru 2011
