摘要

The cyclic deformation of Commertially pure ultrafine-grained titanium obtained by severe plastic deformation through equal channel angular pressing (ECAP) is investigated. Both stress- and strain-controlled experiments were carried out to access the fatigue performance in terms of Wohler diagram, fatigue limit, Coffine-Manson plot and cyclic hardening curves in a range of plastic strain amplitude from 7.5 X 10~(-4) to 10~(-2). A significant enhancement of fatigue limit and fatigue life is found under constant stress testing. No cyclic softening and degradation in the strain-controlled experiments is noticed in titanium contrary to wavy slip materials such as copper subjected to ECAP.
