  1. Abbreviations: BMG, bulk metallic glass; G/B, shear modulus/bulk modulus; Tfc, critical fictive temperature; Tg, glass transition temperature.
  2. Tfc is experimentally determined from the bending plasticity of relaxed samples. G/B is calculated from the ultrasonic measurements on the as-cast samples.
