to the Gibbs free energy difference between liquid and crystal, a thermodynamic glass-forming ability(GFA) parameter related to characteristic temperatures, onset crystallization temperature(Tx...: glass-forming ability; bulk metallic glass; Gibbs free energy  ......
energy of formation, volume expansion work and variation in potential energy with temperature. If the generalized vibration free energy is neglected, the AG-Gibbs energy partition function becomes... obtained by the AGA-potential free energy function of the alloy is higher than the path obtained by the AGA-Gibbs free energy function, because the is always lower than the corresponding  ......
was investigated. The molar Gibbs free energy function of mechanically activated samples was calculated from the structural defects such as amorphization, dislocation and surface energy. According to the molar Gibbs free energy function, the equilibrium temperature of mechanical reduction of silver oxide milled for 21 h was estimated at about 304 K. Consequently, at this temperature silver oxide......
