Abstract

The microstructure and microsegregation of 45CrNiMoV hot-rolled and normalized steel were studied by optical microscope, scanning electron microscopy and EDS. The results show that the severest segregated element is Mo in the tested steel; and 920°C for 20 h is the most appropriate normalizing process for the tested steel as it ensures homogenizing effect; Two residual segregation parameter models were studied and it is proved that homogenization process of 45CrNiMoV normalized steel can be effectively predicted and evaluated by the first residual segregation parameter model, which basically agrees with the experimental results.
