摘要
The purpose of the paper was to summarize the role of microalloying additions in the microstructure evolution control in ferrite-pearlite HSLA steels. The emphasis was placed upon employing high nitrogen content to increase grain refinement and precipitation strengthening in these steels. A complicated nature of the precipitation processes of carbonitrides at different technological stages of steel processing, and its relevance to the microstructure evolution and the mechanical properties of a final product was discussed. It was shown that increasing nitrogen content up to 150 - 200 ppm increased strength properties of steels treated with V, Ti and Mb compared to the steels with low nitrogen contents.
