Abstract
The bainite ductile cast iron with given composition was quenched to get bainite structure. The nucleating position of bainite and the distribution of alloying elements in the matrix were measured. The results show that the bainite nucleates at the interface between graphite and austenite during quenching. Based on the experimental results and thermodynamics, the nucleating mechanism of bainite in ductile iron was analyzed.
