Abstract: This study deals with the grain refinement of the LM25 alloy by means of the addition of a 96Al-2Nb-2B master alloy. Nb-based intermetallics contained in the master alloy act as potent heterogeneous nucleation substrate for the nucleation of primary Al dendrites. The addition of the 96Al-2Nb-2B master alloy to the LM25 alloy permits to significantly refine its microstructural features and the refinement is achieved in a great range of cooling rates. The formation of columnar grains at slow cooling rates is prevented.
