Abstract: Low-carbon, medium-nitrogen 316 stainless steel is a principal candidate for a main structural material of a demonstration fast breeder reactor plant in Japan. A number of long-term creep tests ...

Abstract: A simple elastic-plastic constitutive model based on the two-surface theory is developed to describe deformation behavior of austenitic stainless steels under multiaxial cyclic loading. Dependency ...

Abstract: HCM12A (ASME Grade 122) is used for boiler components in thermal power plants because of its high creep strength. However, a type IV creep damage formed in the heat-affected zone can cause ...

Abstract: There are several codes, standards, handbooks, and guidelines for the nuclear power plant maintenance in Japan, the US, and EU. They include Stress Corrosion Cracking (SCC) and fatigue crack ...

Abstract: Creep strength of welded joint for high Cr ferritic heat resisting steels decreases due to Type-IV failure in heat-affected zone (HAZ) during long-term use at high temperatures. In order to ...

Abstract: The creep strength of welded joints in high Cr steels decreases due to the formation of Type IV creep damage in heat-affected zones (HAZs) during long-term use at high temperatures. This paper ...
