Grain refinement by inoculation is well established in Al alloys and the benefits of grain refinement are widely acknowledged. In contrast in the Cu-system, there has been little practical work performed on the grain refinement of Cu-based alloys. Moreover, there is a lack of detailed investigation to understand the grain refinement mechanism in Cu alloys, due to significant influences of the casting conditions, the impurities and the alloying elements on the alloy under investigation. Grain refinement requires both growth restriction and heterogeneous nucleation. Here, only the aspect of grain refinement by growth restriction will be highlighted in this contribution. The influence of elements with varying segregation power, respectively growth restriction factor (Q), on the grain size of pure copper (99,9 %) under defined cooling conditions as given by the TP-1 test, will be shown.
