Creep-fatigue of P92 in service-like tests with combined stress- and strain-controlled dwell times

Experimental data from service-like creep-fatigue experiments on grade P92 steel

“…They led to the sophisticated, test-specific stress-strain relations shown in Fig. 1 : Strain-controlled relaxation fatigue (RF) test with strain-controlled three-minute dwell times (DT) at minimum and maximum strain (referred to as DT min and DT max ) in each cycle [1 , 2] ; service-like relaxation fatigue (SLR) with strain-controlled three-minute DT min and DT max and additional 30-minute dwells at constant strain (ε = 0, which represent steady-state operation (therefore designated as SSO(SLR) periods) [1] , and service-like creep-fatigue (SLC) with strain-controlled three-minute DT min and DT max and additional 30-minute dwells at constant stress [σ(ε = 0)] (designated as SSO(SLC) periods) [1] . …”

“… This article refers to the research article entitled “ Creep-Fatigue of P92 in Service-Like Tests with Combined Stress- and Strain-Controlled Dwell Times ” [1] . It presents experimental mechanical data from complex service-like creep-fatigue experiments performed isothermally at 620°C and a low strain amplitude of 0.2 % on tempered martensite-ferritic grade P92 steel.…”
