Inoculation of spheroidal graphite cast iron (SGI) is used for improving casting performance and eliminating solidification microporosity by controlling graphite nodule nucleation. In this seminar, we will discuss basic of thermodynamic predictions of non-metallic inclusion formation during ductile iron liquid metal processes, describe a new methods of automated SEM/EDX inclusion analysis, how to get information about graphite nuclei family. High resolution TEM will show you complicated structure of individual nuclei, you will see atomic interfaces in great details. We will also introduce method of 3D micro CT visualization of graphite nodules in cast structure and demonstrate advantages of 3D methods compare to 2D analysis. Finally, we will shear with you the results of study effect of melt inoculation on microporosity in casting
