Abstract

Ductile iron is a pseudo-binary alloy of iron and carbon where the carbon is precipated in the form of 
nodules (spherical) graphite. The ductile iron, thanks to the specific form of graphite, has a good 
combination of properties such as elongation, yield strength, good toughness, castability and 
mechanical workability. Except of graphite, the microstructural components: ferrite, pearlite, 
austenite, martensite or a combination of those microstructures have the greatest influence on the 
mechanical properties of ductile iron. The paper describes influence of the heat treatment that is 
ferritizing annealing on the microstructure and the mechanical properties of ductile iron.
