Abstract
A multi-component model was applied to predict the cyclic stress-strain response of different alloys under thermomechanical fatigue conditions based upon isothermal hysteresis loops. A ductile AISI 304 L-type stainless steel and two high strength alloys, the near-α titanium alloy IMI 834 and the nickel-base superalloy IN 100, were chosen as test materials. These represent alloys with rather different dislocation slip modes, stress-strain characteristics and damage mechanisms. Model predictions are compared with experiments and the differences in cyclic stress-strain response and damage mechanisms under isothermal and thermomechanical fatigue conditions, respectively, are discussed based upon micro structural observations.
