摘要: A new thermodynamic expression for Gibbs free energy difference ΔG between the under-cooled liquid and corresponding crystals of bulk metallic glasses was derived. The newly proposed always gives results in fairly good agreement with experimental values over entire temperature range fusion Tm glass transition Tg Pd40Ni40P20, Pd40Cu30Ni10P20 Pd43Cu27Ni10P20, which possess different heat capacities. However, TS KN expressions cannot provide values. In addition, deviations calculated by at are smaller than those given other all studied. Cu- (9-11) , Nd- (12,13) Fe- (14-16) Ti- (17) Ni- (18,19) Pr- (20) Co- (21) Ca- (22) Ce-based alloys (23) excellent glass-forming ability. (∆G) crystallization these multi-component systems is an important parameter nucleation processes. frequency has exponential dependence on ∆G, hence estimation ∆G often critically when analyzing phenomena. change played role predicting ability alloys. dependences region can be obtained if capacities crystalline phases known. meta-stable nature phase makes it diffi cult to obtain capacity data accurately, although many attempts have been made (4-6) . Therefore, absence functional must estimated theoretically. there no universal applicable derive analytical
