Abstract: Duplex stainless steels are indispensable in marine, energy, and chemical applications, yet their mechanical reliability remains constrained by phase balance and texture, with effective pathways for integrated microstructural optimization still elusive. This study proposed a novel approach for multiscale microstructural optimization in duplex stainless steel via the introduction of trace nanoceramics. The in-situ synthesized and incorporated nanoparticles orchestrated microstructural evolution during solidification by acting as heterogeneous nucleation sites while simultaneously restricting dendritic growth and suppressing secondary-phase coarsening though solute confinement and interface pinning. During hot deformation and solution treatment, nanoceramic-mediated austenite boundary generation promoted recrystallization nucleation, while simultaneous grain pinning ensured phase ratio equilibrium and texture randomization. Nanoparticle-induced local stress field modulation reduced stacking fault energy, thereby facilitating dislocation rearrangement and coordinating interphase recrystallization to mitigate residual stress. Compared to the matrix steel, the reinforced steel exhibited improvements of 16.6 %, 9.5 %, 2.2 %, and 4.64 % in yield strength, tensile strength, fracture strain, and impact toughness, respectively, at room temperature. The strength contributions from grain refinement, the Orowan mechanism, thermal mismatch strengthening, and load transfer strengthening. This study establishes a novel processing paradigm for microstructural harmonization in dual-phase alloys. [ABSTRACT FROM AUTHOR]
