Abstract
In order to evaluate the validity and limitations of the creep-hardening surface model proposed by the present authors, a series of creep tests for type 304 stainless steel were performed at 600°C under various non-steady multiaxial loadings. The test time and the interval of stress change were 960 hr and 48 or 96 hr, respectively, and five kinds of stress histories consisting of randomly varying stress magnitude, stress direction and interval of stress change were employed. It was found that the creep-hardening surface model describes sufficiently well the creep behavior observed in this work.Keywords
