The “fragile”–“strong glass” transition in Al-based alloys is observed as a function of Sc content. The Sc-bearing alloys suffer glass transition as well as Sc-free Al0.84Y0.09Ni0.05Co0.02 alloy, however, the value of ΔCp decreases drastically and comes within the variation of the baseline at higher than 2 at. % of Sc. The studied glasses are free from pre-existing nuclei.

    By means of the enthalpy recovery experiments in a Zr[sub 65]Al[sub 7.5]Cu[sub 27.5] metallic glass, the glass transition process was found to correlate with an obvious variation of enthalpy change with the annealing temperature. With this correlation, we developed an approach to determine the...
