Oregon State University proposes to develop new capabilities to the MARMOT code in order to predict mechanical and corrosion properties of dual-phase stainless steels as a function of composition, aging time, and temperature. The model will be trained and validated by an extensive experimental database of duplex stainless steel alloys, where aging, mechanical properties and atom probe characterization are already complete. Additional corrosion experiments will be performed on aged alloys in PWR water chemistry to provide the corrosion data training set.
