behaviour of pure copper (99.99%) processed by equal-channel angular pressing (ECAP). Coarse-grained pure
copper was processed by 1 and 8 ECAP passes at room temperature. The ECAP-processed specimens were
annealed at room temperature for 3 years. Microstructures of ECAP-processed specimens and their room
temperature-annealed states were investigated by electron back scatter diffraction (EBSD) technique. Tensile
tests were performed at room temperature under constant rate and at 373 K in creep under constant load. It was
found that long-term annealing at room temperature led to occurrence of large grains in microstructure which
influenced the strength. The influence grew with number of ECAP passes.Pracoviště Ústav fyziky materiálu Kontakt Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Rok sběru 2018
