VARIATIONAL CALCULATION OF THERMODYNAMIC PROPERTIES OF SUPERCOOLED LIQUID METALS
过冷液态金属热力学性质的变分计算

By means of the Gibbs-Bogoliubov (GB) thermodynamical variationalcalculation, the thermodynamical properties of the liquid metals as supercooled sta-te, such as Al, Ga, Tl in the 3rd family of periodic table and transition metal Tiwere calculated using the hard-sphere (HS) system as reference. The values of meanatomic volume, Helmholtz free energy, internal energy and entropy as well asspecific heat at constant volume, isothermal bulk modulus, thermal expansion co-efficient and specific heat under constant pressure were determined. The glass tran-sition temperature, T_g, is easily obtained from c_p-T plot. The glass forming abili-ty for metal can be predicted with T_g/T_m, which is in agreement with the experi-mental results.
