摘要
In this work, the best glass former in a binary Gd-Co alloy system has been designed by thermodynamic parameter gamma*, which has been proved to be valid in the prediction of glass forming ability (GFA) of other binary alloys. A metastable phase has been observed in some Gd-Co melt-spun ribbons and its composition has been ascertained. By analyzing the effect of the metastable phase on the GFA of the Gd-Co binary alloys, we predict the Gd50Co50 alloy as the best glass former in the binary alloy system. The prediction has been confirmed by the experimental results, proving the validity of the parameter gamma* in the Gcl-Co binary alloys.
