It has been shown that the heat treatment of 1095°C/640 °C type of ferritic ductile iron with small addition of 0.08% vanadium permits to obtain of the rounded VC nanoparticles with an average size of 50 nm and 0.13 volume fraction. Results of investigations of influence of small vanadium up to 0.3%, niobium up to 0.16% and nitrogen up to 58 ppm additions and heat treatment of 1080°C-24h/640°C and 1080°C-24h/600 °C type on structure and mechanical properties (tensile strength, yields strength and elongation) of ductile iron are also presented in this work. It has been demonstrated that heat treatment and small additions of vanadium, and niobium as well as nitrogen enable to obtain material, which can be classified a EN-GJS-450-18 to EN-GJS-700-2 grade ductile iron.
