Study of Coalescence and Spheroidization of the Dispersed Phase SnSb

摘要

The coalescence and spheroidization of the phase SnSb in binary Sn-Sb alloys (Sn-15% Sb & Sn-20% Sb) was investigated. Both slow and rapidly-cooled alloys were annealed at 160, 200, and 220C. The number of particles and average radius of the dispersed phase were determined per unit volume. Mechanisms of coalescence and spheroidization are postulated from the experimentally determined kinetic curves for both types of quenching procedures. Parameters for the prediction of partical growth are put forward.
