Abstract
In this work, an experimental verification for the transition theory from gray to white cast iron solidification is presented. Experimental tests have been implemented using plate- and wedge-shaped castings of various sizes. The experiments included inoculated and noninoculated cast irons of different chemical compositions and time-temperature histories of the inoculation effects. In addition, thermal-analysis tests were employed to determine the degree of undercooling of graphite eutectic (ΔT m ). This included microstructural evaluations in order to establish the eutectic-cell densities. This procedure enabled the calculation of the theoretical chill width (w), as well as the chilling tendency (CT) of cast iron. It was found that the predictions of the theoretical analysis are in good agreement with the experimental outcome for the chill exhibited in wedge- and plate-shaped castings.
