    Abstract

    We have identified a growth process of nanocrystalline grains in amorphous Al87Ni10Ce3 by means of differential scanning calorimetry and transmission electron microscopy. The grain size of the final grown Al was estimated to be ∼15 nm. A typical nucleation-growth process was observed during the transformation in an amorphous Al85Ni 10Ce5. The grain growth process was only observed in Al-enriched alloys (Al ≳ 87 at. %), indicating that the nuclei pre-existed in an Al-enriched area in the original amorphous state.
