Role of core–shell boron distribution in the long-term stability of M23C6 precipitates in modified 9Cr–1Mo steel

Boron (B) improves the creep resistance of ferritic–martensitic steels by suppressing coarsening of M 23 C 6 precipitates, though the mechanism remains unresolved. Using 3D atom probe tomography on tempered and aged modified 9Cr–1Mo steel, we report, for the first time, a core–sh...
