Japan Atomic Energy Agency (JAEA) has developed 9Cr-ODS martensitic steel and has succeeded in manufacturing thin-walled tubes that overcome highly anisotropic properties. Previous studies revealed that the 9Cr-ODS steel has a dual phase structure consisting of residual-ferrite and martensite. Improvement in creep strength is apparently caused by the retention of the phase, in which ultrafine oxide particles are dispersed. In this study, we have investigated the nanometer-scale microstructure of a dual phase 9Cr-ODS steel by the 3D atom probe operated with femtosecond laser pulses and compared the dispersion state of oxide particles in residual-ferrite and martensite phases.
