Abstract
Effect of addition of RE to Fe-25Cr-6Ni-3Mo-0.25N duplex stainless steel (DSS) on the refinement and globulization of the inclusions to small-smooth sizes are presented. The RE has more positive influence than nitrogen on segre-gation of impurities in DSS. The grain sizes are reduced after RE addition. The smallest grain size attained is 8.4mm when the RE content is about 0.07%. The REs are ferrite formers leading to the increase of phase amount with increasing RE addition. Nitrogen has negative effect to form & ferrite while the REs have positive effect to form & ferrite. The REs refine nitrides and the carbide amount decreases with increasing RE addition to duplex stainless steel Fe-25Cr-6Ni-3Mo-0.25N
