N2 - The In this study, duplex stainless steel containing 5 vol% TiN nanoparticles was fabricated by means of spark plasma sintering (SPS). The effect of sintering holding time, microstructure, density, microhardness, corrosion and wear was investigated. The results showed that ferrite and austenite were the dominant phase. New phase of chromium nitride precipitated (Cr2N) was formed when sintering holding time was increased above 5 min. The volume fraction of the precipitated nitrides increased with the increase in the holding time. The microhardness and density of the composites was increased with the increase in holding time. The corrosion resistance of the composites degraded with the increase in the holding time while, the best wear performance was attained with 10 min holding time.
