Experiments were conducted to investigate the low‐cycle deformation behavior of an ultrafine‐grained (UFG) Ti–6Al–4V alloy produced by severe plastic deformation (SPD) through a combination of equal‐channel angular pressing (ECAP) and extrusion. The fatigue properties were examined by stress‐controlled fatigue testing at stress amplitudes in the range of 700–1050 MPa. The specimens exhibited a dimpled final overload fracture mode. The results show the UFG alloy has a longer fatigue life and a finer dimple size than the coarse‐grained material.
