Abstract
The objective is to determine if scandium additions can create nodular or compacted graphite iron. Initially, plates of uninoculated cast iron with and without scandium additions were assessed metallographically, and scandium was found to form type D graphite morphology. Both materials were carbidic. Subsequently, a designed experiment was formulated to determine the effect of scandium level on eutectic and hypereutectic cast iron. Cast iron alloyed with 0.01 wt% scandium contained more type D graphite than the baseline, while cast iron with 0.26 wt% scandium was completely carbidic with little graphite present.
