The factors influencing GFA (glass-forming ability), and separated as intrinsic (belonging to glass itself), and extrinsic (depending upon external conditions) factors was studied. The study also considered the solidification of metallic liquid phase by casting. The time-temperature cooling curve of pure Ni cast into Cu mold was obtained by recording the temperature of the melt with a thin K-type thermocouple, which was connected to an analog-to-digital signal converter. The thermal expansion treatment was applied to Ni and a high value of the reduced glass-transition temperature of about 0.6 was found. Intrinsic factors assume that homogeneous nucleation competes with glass formation, and include a number of fundamental and derived thermal parameters, physical properties, and a topological contribution from different atomic packing.
