24 electron cluster formulas as the ‘molecular’ units of ideal metallic glasses
TL;DR: In this paper, it was shown that the number of electrons per unit cluster formula, e/u, is universally 24 and that the origin of different electron number per atom ratios e/a is related to the total number of atoms Z in unit cluster formulas, i.e.

Bulk Glass-Forming Metallic Alloys: Science and Technology
TL;DR: The MRS Medal was presented by William L. Johnson at the 1998 MRS Fall Meeting on December 2, 1998 as discussed by the authors, where Johnson received the honor for his development of bulk metallic glass-forming alloys, and the fundamental understanding of the thermodynamics and kinetics that control glass formation and crystallization of glassforming liquids.

Under what conditions can a glass be formed
TL;DR: The glass-forming tendency of a given material is determined principally by a set of factors which can be specified to some extent in the laboratory, namely, the cooling rate, - T, the liquid volume, v], and the seed density, ps and depending upon the materials constants: the reduced crystal-liquid interfacial tension, α the fraction, f, of acceptor sites in the crystal surface, and the reduced glass temperature, Trg.
