In an individual alloy system for marginal metallic glasses (MGs), the fragility of supercooled liquids (m) is inversely proportional to the fragility of superheated melts (M), which depends on the differently inherent characteristic temperatures. The more stable the superheated melt, the more fragile the supercooled liquid becomes and the better the glass-forming ability (GFA). The strong supercooled liquids correspond to the bad GFA resulting from heterogeneous nucleation in liquids. For the whole Al-based MGs, m has general linear relations with the GFA and M, respectively.
