Abstract
The as quenched metallic glass Fe46Ni31VlSi8B14 has been investigated by atom probe field ion microscopy. The results have shown that the material had separated into a fine-scaled mixture of a boron and silicon-rich phase and an iron-enriched phase. Their chemical compositions have been determined. The composition profile of the specimen revealed that the characteristic length of the two-phase-structure was in the order of 10 nm. It is proposed that the observed structure originated from the nucleation and growth of molecular cluster-like zones in the material.
