A new thermodynamic model for estimation of glass forming ability (GFA) is proposed. Considering both the stability of liquid and crystal and the competition of glass and crystal, an expression of GFA has been obtained. The equation is very useful for identifying alloy compositions with good GFA of
Based on the consideration of the liquid phase stability, the resistance to crystallization and the glass transition enthalpy, a new criterion Q, defined as ((T g + T x )/T l )โข( E/ H), where the T g , T x , T l , E and H are the glass transition temperature, the onset crystallization temperature, t
As the reliability criterions of glass forming ability (GFA) for Fe(Co)-based bulk metallic glasses (BMGs), the temperature interval of the supercooled liquid region T xg , the reduced glass transition temperature T rg and the parameter were evaluated by the linear regression with the critical diame
The thermal stability, glass forming ability and mechanical properties of Cu-Zr-Al-M (M = Ag, Be) bulk metallic glass alloys have been investigated. The glass forming ability in the Cu-Zr-Al-M (M = Ag, Be) alloys increased proportionally to the Ag or Be content and show good correlations with therma
