Formation of microstructure of Bi-40 wt. % Sn alloy during hightspeed crystallization

Abstract

Rapidly solidified foils of Bi — 40 wt. % Sn have homogeneous distribution bismuth and tin phases with microcrystalline structure. Its formation is caused by the spinodal decay of supercooled supersaturated liquid solution and subsequent nucleation and growth of centers of crystallization in areas rich in bismuth and tin.
