Abstract

The results of microstructure and texture studies into Sn–Bi and Sn–Pb eutectic alloys produced at melt cooling rates of 2 and 5 × 105 K/s are presented. Ultrafast quenching from the melt is found to initiate the formation of microcrystalline structure. The causes of the transition from the lamellar to the microcrystalline structural phase and the generation of nucleation texture are discussed.
