Abstract
The complex effect of copper on structure formation in cast iron is analyzed. It is shown that the action of copper can be not only graphitizing but also chilling. Theoretical and experimental methods are used for investigating the mechanisms of the different copper effects. Special features of structure formation in copper irons during their crystallization are studied with the use of designed sections of the Fe-C-Cu diagram. It is shown that the mechanisms of the pearlite-forming and anti-graphitizing actions of copper have a more kinetic nature than a thermodynamic one.
