To clarify the effects of grain refinement on the growth behavior of small surface cracks, fatigue tests on round bar specimens were conducted on coarse-grained (CG) copper and ultrafine-grained (UFG) copper processed with equal channel angular pressing. The growth behavior of a small crack was monitored using a plastic replication technique. The difference in the growth behavior tendency between the CG and UFG copper occurred at an extremely low fatigue crack growth rate (FCGR) of dl/dN |

For the UFG copper, the FCGR temporarily dropped at around dl/dN=3×10−7mm/cycle and then gradually recovered with subsequent cycling.

To understand the reason for the temporary decrease of the FCGR of UFG copper, a crack growth model based on the reversible plastic zone size at a crack tip and the related microstructural factors were developed.
