“…However, most of those studies focused on the ratchetting deformation produced in pure fatigue loading condition. In terms of ratchetting deformation under creep-fatigue loading, Yoshida et al (1989) and Yoshida (1990Yoshida ( , 1995 had conducted some tests for 304 stainless steel at room temperature and 923 K, and reported the effect of stress rate, peak stress hold and stress ratio on the ratchetting deformation. Their results indicated that the evolutions of ratchetting strain for different stress ratios and a constant peak stress hold were almost the same when the stress ratio was larger than À0.4 (the static creep test can be referred to as experiment with stress ratio of 1), which is similar to our experimental results except for the case of static creep as shown in Fig.…”

“…Ratchetting taking place under uniaxial cyclic loading with nonzero mean stress is referred to as uniaxial ratchetting, which is most fundamental and has been studied in many works. For 304 and 316 stainless steels, uniaxial ratchetting experiments have been reported by Yoshida et al (1988), Chaboche and Nouailhas (1989), Krempl (1989, 1990), Yoshida (1990), Sasaki and Ishikawa (1993), Delobelle (1993), Delobelle et al (1995), Haupt and Schinke (1996), and so on.…”

Uniaxial ratchetting characteristics of 316FR steel at room temperature are studied experimentally. Cyclic tension tests, in which maximum strain increases every cycle by prescribed amounts, are conducted systematically in addition to conventional monotonic, cyclic, and ratchetting tests. Thus hysteresis loop closure, cyclic hardening and viscoplasticity are discussed in the context of constitutive modeling for ratchetting. The cyclic tension tests reveal that very slight opening of hysteresis loops occurs, and that neither accumulated plastic strain nor maximum plastic strain induces significant isotropic hardening if strain range is relatively small. These findings are used to discuss the ratchetting tests. It is thus shown that uniaxial ratchetting of the material at room temperature is brought about by slight opening of hysteresis loops as well as by viscoplasticity, and that kinematic hardening governs almost all strain hardening in uniaxial ratchetting if stress range is not large.

“…Ratcheting can be defined as the directional and progressive accumulation of strain under asymmetrical stress-controlled cycling (Jiang and Zhang, 2008). To understand this phenomenon, several research works have been carried out at uniaxial cyclic loading with non-zero mean stress for 304 and 316 stainless steel at room and high temperatures has been reported by (Yoshida et al , 1988; Chaboche and Nouailhas, 1989; Ruggles and Krempl, 1989, 1990; Delobelle, 1993). Majority of available literature on ratcheting behavior pertains to studies on piping materials like SA333 (Paul et al , 2010a, 2010b, 2011a) and austenitic steels (Feaugas and Gaudin, 2004; Kang et al , 2005; Bocher et al , 2001; Yang, 2005; Paul et al , 2011b, 2012; Taleb and Cailletaud, 2011; Ray et al , 2010; Kang and Gao, 2005; Kang et al , 2002a, 2002b; Polák et al , 2012).…”

Purpose The purpose of this paper is to study the effect of mean stress and stress amplitude on the asymmetric cyclic deformation behavior of SA333 Gr-6 C-Mn steel. Such type of loading may arise during the service period because of the load fluctuations, thermal gradients and sudden loading like seismic events. Tests were also carried out at different temperatures to understand the effect of it on sensitiveness of the materials deformation behavior. Design/methodology/approach Cylindrical specimen of 8-mm gauge diameter and 15-mm gauge length was fabricated from the pipe section along its axis. Stress controlled ratcheting tests were carried out by using triangular waveform for cyclic loading. The strain accumulations were measured using 12.5-mm gauge length extensometer. Ratcheting tests were carried out at fixed stress amplitude of 400 MPa and mean stress varying from 0 to 75 MPa, whereas at the fixed mean stress of 100 MPa and stress amplitude varies from 300 to 400 MPa at 300°C. To study the effect of temperature on ratcheting behavior, tests were carried out at a load of 100 MPa mean stress and 350 MPa stress amplitude, with a varying temperature between room temperature and 350°C. The stress rate of 115 MPas-1 was kept constant for all the tests. Findings Increase in mean stress and stress amplitude, ratcheting strain and plastic strain amplitude increases, whereas ratcheting life decreases. With an increase in temperature, ratcheting life increases and strain accumulation decreases up to 300°C, whereas on further increase in temperature, strain accumulation increases with reduction in ratcheting life. Minimum ratcheting rate was observed at 250°C and 300°C. The dynamic strain aging (DSA) phenomena lead to the hardening of the material. The investigated steel shows DSA temperature regime lies between 250°C and 300°C. The failure modes at 250°C and 300°C temperature was transgranular, whereas at 350°C complete ductile. Research limitations/implications The stress rate and loading condition may vary to study the ratcheting behavior. Practical implications From this study, the critical cyclic load may be determined. The DSA temperature regime of this material is determined at this stress rate. This could help to evaluate the cyclic deformation behavior of the material with temperature changes. Originality/value In this investigation, the DSA temperature regime has been determined where maximum ratcheting life, minimum strain accumulation and ratcheting rate were observed. The critical load where the minimum life of the material occurred at elevated temperature is 100 MPa mean stress and 400 MPa stress amplitude.
