Abstract

Studies of the effect of heat treatment on the performance properties of ductile iron with nodular graphite have been carried out. Annealing was carried out in order to increase the strength properties of the material, as well as plasticity and impact strength. The paper presents the results of microstructural analysis of high-strength cast iron VCH 35 after heat treatment. The conducted studies have shown that in the process of heat treatment, which is high-temperature annealing, it makes it possible to increase the degree of globularity of graphite inclusions, as well as to increase the degree of perfection of their microstructure. In addition, the conducted annealing led to the elimination of pearlite colonies with sizes less than 1-1.5 µm.
