Abstract

A combination of an automated SEM/EDX analysis, a special 2D-3D converter of nodule size distribution, and adaptive thermal analysis were used for the study of heterogeneous nucleation in ductile iron. The special quenching technique was applied to increase probability to reveal non-metallic heterogeneous nuclei in small graphite nodules. Ternary diagrams were developed to compare statistics of oxide and sulfide compositions in graphite nodules and metal matrix. Thermodynamics of heterogeneous nucleation of graphite phase in Mg-treated cast iron is discussed based on the novel experimental data.
