NEUP CINR-22-26757: Role of Heterogeneity in Manganese and Nickel Rich Precipitate Distribution on Hardening of Reactor Pressure Vessel Steels: Integrated Modeling and Experimental Characterization

The hypothesis of this work is that the different nucleation and coarsening kinetics of manganese and nickel rich precipitates (MNPs) compared to copper rich precipitates, and the heterogeneous distribution of manganese and nickel rich precipitates on or near dislocations, both lead to unique hardening behavior at high neutron fluence. The objective of this work is to understand hardening in reactor pressure vessel steels caused by MNPs via integrated multiscale modeling and experiments.
