... behavior. This work presents the cyclic R–O material hardening parameters for 316 stainless steel similar metal welds. The parameters were estimated under various conditions (in-air at room temperature, 300 °C in-air, and in-air at primary water conditions for a pressurized water reactor (PWR...

... oxidation rate law at the crack tip. Crack growth rates of Ni-base alloys and weld metals in pressurized water reactor primary water environments are formulated with the theoretical crack growth rate model by combining the crack tip mechanics and the quasi-solid state oxidation rate law...

... pressurized water reactor boiling water reactor theoretical modeling crack tip strain rate Nickel-based alloys are widely used as structural materials in nuclear power plants. Primary water stress corrosion cracking (PWSCC) of thick-wall pressure boundary components such as vessel head penetrations...
