Abstract
The effect of alloying elements and microstructure on the dynamic strain aging (DSA) behavior of 1.25Cr-0.5Mo (P11, ASTM 335Gr.P11) and 2.25Cr-1Mo (P22, ASTM 335Gr.P22) steels was investigated. For both steels, different cooling conditions such as air-cooling (AC) and oil-quenching (OQ) were applied. Tensile tests were conducted in the temperature range..... More

Abstract
Three 304L austenitic stainless steel feedwater heater (FWH) tubes used in pressurized water reactors (PWRs) were investigated in this study. By comparing metallurgical differences, such as microstructural features, micro-hardness, and circumferential residual stress of the failed and non-failed FWH tubes by stress corrosion cracking (SCC), factors which could affect SCC.....

Abstract
347 austenitic stainless steel weld (ASSW) was thermally aged at 343, 400 and 450 °C up to 20,000 h in this study. Effects of thermal aging induced microstructure evolution on the mechanical properties and corrosion resistance of delta-ferrite in the 347 ASSW were qualitatively and quantitatively assessed by high resolution.....
