Abstract
Glass forming ability (GFA) for the formation of metallic glasses was evaluated on the basis a of time-reduced temperature transformation diagram using reduced parameters. A equation was proposed for the evaluation of GFA which included a viscosity term at melting temperature (Tm) for calculating the critical cooling rate (Rc) of pure metals and two probability terms incorporated with the thermodynamic quantities. The probability terms were introduced to account for the decrease in Rc for metallic glasses. The results showed that the viscosity at Tm was a key factor for the formation of metallic glasses.
