Notes:
The thermal stability and crystalline phases precipitated from the as-cast rods of theCu50Zr50-based alloys with addition of Al or simultaneous addition of Al/Ti or Al/Ag elementswere investigated using DSC, DTA and XRD. The value of [removed info]Tx, Trg and γ as a function of alloycomposition shows a same trend, in which the Cu46Zr46Al8 alloy exhibits the largest value of [removed info]Tx,Trg and γ. However, this trend is different from the variation of the dc with alloy composition, inwhich the Cu42Zr42Al8Ag8 alloy has the largest dc for glass formation. Trg′ based on Tg/Tm has agood correlation with the critical diameter for glass formation in this alloy system. It was foundthat the alloy with higher GFA has more complex precipitated crystalline phases from the as-castrod with a diameter larger than the critical diameter for glass formation
