Uniaxial static and cyclic creep tests are carried out on a bainite 2.25Cr-1Mo steel at 455°C. The dependence of cyclic response on varied unloading conditions is investigated, with unloading rates from 0.6 MPa/s to 39 MPa/s and the valley stress duration from 0 to 30 min. Fracture surfaces of each specimen are analysed by using a scanning electron microscopy, and a systematic classification of strain components under cyclic creep is proposed to determine the actual damage.
