| Abstract: | The nodular eutectic in the austenite bainite steel is pseudo eutectic of austenite and (Fe,Mn) 3C, which is formed between austenite dendrites at the end of the solidification because of the segregation of C and Mn. By thermodynamics calculation, two dimensional lattice misfitting calculation and observations of transmission electron microscope(TEM) and scanning electron microscope(SEM), it is shown that CeO 2 and CeAlO 3 may act as the heterogeneous nuclei of the nodular eutectic. |
