Grain Structure of Rapidly Solidified Alloy Sn_(32)Bi_(52)Pb_(16)

摘要

Rapidly solidifed foils of Sn~(32)Bi~(52)Pb~(16)alloy consist of liberations of tin, bismuth, and ε phase. The length of most chords of random secants located on sections of tin, bismuth, and ε-phase grains does not exceed 1 μm. The specific surface area of boundaries of grains of all phases is 2.4 μm_(–1). There are clear textures of (100) tin, ( $$10overline {12} $$ 10 12 ¯ ) bismuth, and ( $$10overline {10} $$ 10 10 ¯ ) ε phase.
