Conclusions 1. The first additions of vanadium up to 0.04% in low-pearlite steel of the 09G2 type lead to larger amounts of dispersed phases due to the formation of V(CN), which promotes ferrite grain refining. 2. With increasing amounts of vanadium over 0.04% the quantity of V(CN) increases due to the smaller quantity of nitrogen bound with A1N and carbon bound with iron (Fe3C). 3. When the vanadium content is raised from 0.04 to 0.26% there is a constant change in the stoichiometric formula of vanadium carbonitride from V(Co.6No.4) to V(Co.9No.1). 4. The first addition of 0.04% V favors a substantial reduction of the ductile-brittle transition temperature and higher fracture toughness of the steel. With increasing amounts of vanadium over 0.4% the fracture toughness decreases and the ductile-brittle transition temperature rises.
