On the Mechanism of Modification of the Aluminum-Silicon Eutectic by Strontium: The Role of Nucleation

  • M. Makhlouf
Article

Abstract

The purpose of this contribution is to demonstrate that the presence of strontium in hypoeutectic Al-Si alloys significantly influences the kinetics of nucleation of eutectic silicon; and therefore, contrary to current belief, a complete theory for the mechanism of modification of the eutectic phases in hypoeutectic Al-Si alloys by strontium must address not only the Growth aspects of the process, but also its Nucleation aspects.

Keywords
