Long-term creep rupture behavior of smoothed and notched bar specimens of low-carbon nitrogen-controlled 316 stainless steel (316FR) and their evaluation

Prediction of creep crack growth behavior in Cr–Mo–V steel specimens with different constraints for a wide range of C∗

“…(4) is usually assumed to be a constant for a given temperature. However, a lot of experimental results and analyses have shown that the creep fracture mechanism depends on stress levels (strain rates), which leads to the stress-regime dependence of the creep ductility of materials [29][30][31][32][33][34][35]. At high stress regime, the creep fracture process is dominated by plasticity controlled void growth, and the creep ductility has an upper shelf value [30].…”

Study on creep-fatigue life prediction methods for low-carbon nitrogen-controlled 316 stainless steel (316FR)

“…Three kinds of products of 316FR used in creep tests (Takahashi et al, 2008) were mainly tested in this study. Two of them, called plate A and plate B hereafter, were produced by hot-rolling and their thickness was 50 mm, which is compa- Chemical composition and average grain size number in ASTM standard of these products are shown in Table 1 with recommended ranges provided for this steel.…”

Unified characterization of in-plane and out-of-plane creep constraint based on crack-tip equivalent creep strain

“…(6) is usually assumed to be a constant for a given temperature. However, a lot of experimental results and analyses have shown that the creep fracture mechanism depends on stress levels (strain rates), which leads to the stress-regime dependence of the creep ductility of materials [46,[52][53][54][55][56][57]. For the Cr-Mo-V steel used in this work, the estimated stress dependent creep ductility is shown in Fig.…”
