STRUCTURE OF THE LAVES PHASE OBSERVED IN POLYSTYRENE LATEXES.

Abstract

This paper describes light microscopic observations of polystyrene latexes with spherical particles of two different diameters, d and 1. 4-1. 9d. Polystyrene latexes are available for simulating structures in intermetallic compounds. An amorphous state appeared for a few hours after stirring or vibrating the latexes and subsequently the Laves phase structure nucleated and grew by Brownian motion of particles whose diameters were d and 1. 4-1. 7d. The structures are classified into MgCu//2 and the MgZN//2 types containing such lattice defects as grain boundaries, dislocations, vacancies or mis-arranged particles.
