Nanostructure formed by phase separation of fcc-Al from eutectic crystallization in the Al85Ni10Ce5 metallic glass

Abstract:

A nucleation-growth control for Al85Ni10Ce5 glass has transformed to a growth control for Al83Ni10Ce5Si2 glass. That’s to say a small quantity of Si addition can successfully separate the Al phase to single precipitate from a eutectic precipitation composited of Al and other intermetallic compound to synthesize nanostructured materials, characteristic of microstructures with finely dispersed nanoccrystalline Al in an amorphous matrix. Favorably，no evident decrease of glass forming ability is observed in the transformation. We suggest that the Si atoms solve into Al lattice to sever as pre-exist nucleus for fcc-Al, in the same time; a nucleation reaction of fcc-Al is accompanied to compensate the nucleation rate.
