THE STRUCTURE FORMATION OF RAPIDLY SOLIDIFIED FOIL OF THE EUTECTIC ALLOY Sn-8,8 WT. % Zn

Abstract

The results are presenred of a study of the microstructure of rapidly solidified foil of the eutectic alloy Sn — 8,8 wt.% Zn A and B surfaces, microstructure parameters are determined. The texture of the precipitates of tin and zinc solid solutions in the foil was studied, and the pole densities of the diffraction lines of these phases are presented. The effect is studied of ultrafast cooling on the distribution of misorientation angles of neighboring and randomly selected grains for surface foil layers in contact with surfaces A and B.
