“…On the other hand, the secondary hardening behavior in PWR water was very similar to that in 310°C air due to effect of dynamic strain aging (DSA). These secondary hardening behavior induced by DSA for several austenitic SSs was also reported under low strain amplitude at high temperatures of approximately 300°C [14,[18][19][20]. Meanwhile, the magnitude of hardening in simulated PWR water is higher than that in air environment because the corrosion-produced and absorbed hydrogen contributed to the DSA in PWR environments, as previously reported for austenitic alloys [11][12][13][14].…”

“…It is manifested by serrated plastic flow in the stress-strain curve under uniaxial tensile loading. DSA has also been observed under creep and fatigue loading [Rodriguez 1984, Srinivasan et al 1991, 1999, Hong and Lee 2004, 2005. DSA is caused by interactions between mobile dislocations and diffusing solute atoms, and its occurrence depends on both temperature and strain rate.…”

This report provides an update on the evaluation of thermal-aging induced degradation of tensile properties of advanced HT-UPS austenitic stainless steels. The report is the second deliverable (level 3) in FY11 (M3A11AN04030103), under the Work Package A-11AN040301, "Advanced Alloy Testing" performed by Argonne National Laboratory, as part of Advanced Structural Materials Program for the Advanced Reactor Concepts. This work package supports the advanced structural materials development by providing tensile data on aged alloys and a mechanistic model, validated by experiments, with a predictive capability on long-term performance.The scope of work is to evaluate the effect of thermal aging on the tensile properties of advanced alloys such as ferritic-martensitic steels, mod.9Cr-1Mo (G91), G92, and advanced austenitic stainless steel, HT-UPS. The aging experiments have been conducted over a temperature of 550-750°C for various time periods to simulate the microstructural changes in the alloys. In addition, a mechanistic model based on thermodynamics and kinetics has been used to address the changes in microstructure of the alloys as a function of time and temperature, which is developed in the companion work package at ANL. The focus of this project is advanced alloy testing and understaning the effects of long-term thermal aging on the tensile properties.The first deliverable of FY11 reported the tensile testing results of thermally-aged G92 in the normalized and tempered condition (H1 G92), G92 in the cold-rolled condition (H2 G92), and reference alloy, G91 ferritic-martensitic steels. This report summarizes the tensile data of thermally aged HT-UPS austenitic stainless steel. Two heats of HT-UPS have been investigated, i.e., solution-annealed HT-UPS (SA HT-UPS) and hot-rolled HT-UPS (HR HT-UPS). Tensile data have been obtained for SA HT-UPS thermally-aged for up to 18031 h at 550°C and for up to 17595 h at 650°C, as well as for HR HT-UPS thermally aged for up to 6909 h at 550°C, 4293 h at 600°C, and 5407 h at 650°C.Major finding are: (1) the solution-annealed HT-UPS showed continued, moderate increase in strength and decrease in ductility with increasing aging time up to 18034 h at 550°C. Thermal aging at 650°C increased the yield stress and decreased the ultimate tensile strength and drastically reduced the ductility in the SA HT-UPS. For the HR HT-UPS, thermal aging at 550°C for up to 6909 h showed little influence on its tensile behavior. Thermal aging at 600°C for 4293 h increased the strength and decreased the ductility. The 650°C-thermally-aged HR HT-UPS specimens showed very different strengthening, strain hardening, and flow localization behavior. Thermal aging at 650°C increased the yield stress but decreased the ultimate tensile stress for the HR HT-UPS. (2) Dynamic strain aging (DSA) was observed in both the solution-annealed HT-UPS and the hot-rolled HT-UPS at temperatures between 550-650°C at a strain rate of 0.001 s -1 . Extensive precipitation in the matrix after thermal aging at 600 and ...
