Sažetak
Studies have been performed on microalloyed steel with three different niobium content: 0, 036%, 0, 048% and 0, 066%. All steels had the same basic chemical composition. Samples for research were taken from different phases of final thermomechanical treatment. The samples were analyzed by transmission electron analysis and X-ray diffraction profile analysis. Precipitation of niobium carbonitrides was observed in all tested samples. In steels with 0, 048% nobium, densely complex carbonitride arrays were observed in the grain and along the boundaries of the crystal grain. The highest degree of interaction between deformation of induced nobium precipitates and dislocations was found in steels with o, o48% Nb. The largest distortion of the crystal lattice was determined on the same samples. In steel with 0, 036% niobium is less pronounced and the crystal lattice distortion is less.
