Synthesis, Interface and Properties of Nanodispersed Aluminum.

Abstract

The work on synthesis and study of phase transformation of the soft phase dispersed in aluminum based matrices was obtained. This research successfully synthesized nanometric dispersions of bismuth (Bi) in a glassy Aluminum-Iron-Silicon (Al-Fe-Si) matrix by using rapid solidification technique. The Bi melt is immiscible with the ternary melt of Al-Fe-Si and phase separates. Thus quenching rapidly through the miscibility gap has enabled to obtain nanometric dispersions of Bi Particles in a glassy matrix. The final result also showed a large depression of the melting point when the sample was recycled in the differential scanning calorimeter (DSC). The depression of the melting point is reversible in nature by cycling the sample from few degrees above the depressed melting point.
