Type 304 Stainless Steel

For the deformation model developed in Part I, material constants are calculated from standard test data on type 304 stainless steel. With them, simulations are made of various types of tests, including tensile tests, strain-rate sensitivity, creep tests with stress drops, strain-controlled cycling, and creep-fatigue interaction. The simulations show general agreement with the corresponding experimental data for type 304, but in a few respects, quantitative improvements are required. Implications of the strengths and weaknesses of the new model are discussed.

This paper studies the biaxial creep damage of type 304 stainless steel at 923 K. Biaxial tension creep tests were carried out using cruciform specimens and the effect of stress biaxiality on rupture lifetime and creep voiding was discussed. Mises equivalent stress and the equivalent stress based on crack opening displacement were a suitable parameter to assess the biaxial creep damage. The equivalent stress proposed by Huddleston overestimated the biaxial creep damage by more than a factor of two. Stress biaxiality had almost no influence on the orientation of voided grain boundaries and the critical value ofparameter A. Tests of alternative loading direction significantly dispersed the biaxial creep damage resulting in larger creep lifetime.

Multiaxial Loadings

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.
