At Southend differences in environment are inferred to restrict the activity of sulphate reducing bacteria, resulting in direct oxidation of steel to generate iron oxyhydroxide gels, which subsequently recrystallise, dehydrate and oxidise to goethite, magnetite and ultimately hematite in both splash zone and intertidal samples.

Results show that additional Mo segregation at cellular boundaries contributes a stronger strengthening effect than Si, which periodically hinders dislocation slip during deformation. Addition of Si triggers deformation twinning at an early stage due to decreased stacking fault energy, and subsequent dynamic Hall-Petch effects improve strain-hardening capability and plasticity for PBF-LB SS 316L+Si. Meanwhile, addition of Mo enhances pitting corrosion resistance of PBF-LB 316L+Mo SS in chloride-containing solutions, especially the pitting re-passivation, which is opposite in the Si addition case due to the increased quantiy of undesired Si/Mn-rich oxides. Underlying deformation and corrosion mechanisms for Mo/Si-added PBF-LB SSs are discussed.
