Abstract

A mechanism that describes nucleation and growth as well as morphology modification by chemical additives of the eutectic phases in aluminum-silicon hypoeutectic alloys is presented. The mechanism is supported with results of nonequilibrium thermal analyses, scanning electron microscopy (SEM) and transmission electron microscopy (TEM), selected area electron diffraction, and elemental X-ray mapping, as well as results of high-temperature rheological measurements that are performed on alloy samples of precisely controlled chemistry.
