On the Formation of Dispersoids during Rapid Solidification of an AI-Fe-Ni Alloy W.J. BOETI'INGER, L. A. BENDERSKY, R. J. SCHAEFER, and E S. BIANCANIELLO Examination of the effect of rapid solidification velocity on the microstructure of AI-3.7 wt pct Nil.5 wt pct Fe has revealed a new mechanism for the formation of discrete second phase particles in rapidly solidified alloys. Cellular growth of a-A1 occurs with the intercellular phase, A19(Fe, Ni) 2 in two distinct morphologies. At low velocity (
