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.
