dc.description.abstract | This paper reports the effect of increase in vanadium (V) content on changes in precipitation reaction and on mechanical properties in SA1017 grade 23 steel (2.25Cr-1.5W-VNbTi) for application to pressure vessels in advanced nuclear reactors. Increase in V content prohibits formation of coarse M23C6 carbide and allows only fine MX carbo-nitrides precipitation in this steel during tempering. Calculation based on Ashby-Orowan equation suggests that increase in yield strength is mainly attributed to precipitation hardening of fine MX carbo-nitrides and it shows a good agreement with experimental results. Meanwhile, step-cooling heat treatment causing temper embrittlement decreases Charpy impact toughness of steels at sub-zero temperatures, but higher V-alloyed steel shows higher toughness. Because interfaces between MX carbo-nitrides and the matrix act as strong trap sites of segregating P, its segregation toward prior austenite grain boundaries is decreased. Therefore, alloy design of V content for SA1017 grade 23 improves strength without degradation of impact toughness and temper embrittlement.
