Effect of free electron concentration on glass-forming ability of Ca–Mg–Cu system

“…One of the bottlenecks for the applications of the BMGs is limited glass forming ability (GFA) of the alloys [1,[6][7][8][9]. Up to now, the criteria deduced from the consideration of thermodynamical factors [10,11], phase diagram [9,12,13], atomic size ratio [14,15] and nearly free electron theory [16] have been proposed to evaluate and predict the GFA. Electron concentration per atom e/a, as a criterion, is related exclusively to fundamental properties of constitute elements, which has stimulated broad interest [17][18][19][20].…”
