Paper Title:
Fatigue Strength of Ultrafine Grained Copper Treated by Post-ECAP Mild Annealing
  Abstract

In order to study the effect of post-ECAP (equal channel angular pressing) mild annealing treatment on fatigue strength of ultrafine grained (UFG) copper, the stress-controlled fatigue tests of UFG copper with and without post-ECAP annealing treatment were performed for a wide range of fatigue life. The evolution of surface damage and growth behavior of surface cracks were monitored by plastic replication technique. The effect of post-ECAP annealing on the fatigue strength was discussed through the observation of changes in surface morphological features.
