Low cycle fatigue characteristics of duplex stainless steel with degradation under pure torsional load
Description
Monotonic torsional and pure torsional low cycle fatigue (LCF) test with artificial degradation were performed on duplex stainless steel (CF8M). CF8M is used in pipes and valves in nuclear reactor coolant system. It was aged at 430 degree C for 3600hrs. Through the monotonic and LCF test, it is found that mechanical properties (i.e., yield strength, strain hardening exponent, strength coefficient etc.) increase and fatigue life (Nf) decreases with degradation of material. The relationship between shear strain amplitude (γα) and Nf was proposed
