Abstract

Abstract

Domestic 508-3 steel is the key material for the pressure vessel of pressurized water reactor. To study the non-proportionally multiaxial cyclic deformation behavior of domestic 508-3 steel at different temperatures, whole-life fatigue tests under multiaxial non-proportionally path with strain and stress controlled were performed on domestic 508-3 steel. Hourglass type and butterfly type non-proportionally paths were chosen in the tests, which revealed cyclic deformation characteristics and ratcheting behavior under different loading paths and different loading conditions. Results show that notable temperature dependent non-proportionally multiaxial cyclic deformation behavior of domestic 508-3 steel can be observed, and due to the effect of dynamic strain aging, the material exhibits cyclic hardening or stable characteristic at 350℃.
