Abstract Comments about a recent publication entitled "Improving glass forming ability of off-eutectic metallic glass formers by manipulating primary crystallization reactions." 'Acta Materialia, 200 (2020) 710-719 by Y. Q. Zeng, J. S. Yu, Y. Tian, A. Hirata, T. Fujita, X. H. Zhang, N. Nishiyama, H. Kato, J. Q. Jiang, A. Inoue, M. W. Chen. The liquidus temperatures Tl of Ni60Pd20P20-y-x SiyBx glass formers are equal to the disappearance temperatures Tn+ of liquid medium-range order resulting from the formation of an undercooled phase behind the glass phase. At this temperature, a volume fraction of about 15%, corresponding to the percolation threshold of configurons, melts accompanied by an endothermic enthalpy.
