摘要: In the study of metallic glasses, it is vitally important for us to understand glass formation and forming ability (GFA). This letter presents a thermodynamic model evaluating in glasses. An expression has been derived from considering both stability amorphous phases resistance crystalline intermetallic phases. equation very useful identifying alloy compositions with good GFA binary other systems. The prediction this verified by experimental Zr–Cu system.
