Creep and Ageing Interactions in Biaxial Fatigue of Type 316 Stainless Steel

Source

A high-strain, biaxial (tension/torsion) fatigue study has been conducted on Type 316 stainless steel at 550°C. The tests were under strain control, some with dwell periods up to 10 min at the positive strain peaks. The deformation and fracture behavior under these conditions revealed a strengthening effect due to the fast carbide precipitation which extended life in some cases. Also it is shown that the form of the multiaxial fatigue failure criterion, modes, and directions of cracking were functions of hold time. The multiaxial cyclic stress-strain curve is best described in terms of shear stress and strain components on the maximum shear plane for a given hold time.
