Original Abstract

The objective of the present work was to study the stability of microstructure of ultra fine-grained (UFG) copper under high-cycle and very high-cycle fatigue loading and under thermal exposition. UFG Cu was prepared by equal channel angular pressing. No grain coarsening was observed after fatigue resulting in failure in the interval from 104 to 1010 cycles. Similarly, no grain coarsening was detected after thermal exposition at a temperature of 180 C for 6 min. The microstructure was examined by electron backscattering diffraction (EBSD) and transmission electron microscopy (TEM)
