摘要	Based on the non-isothermal transformation theory and non-steady state nucleation theory, a new method for calculating the continuous cooling transformation curve and the critical cooling rate of bulk metallic glass alloys is put forward in this paper. The continuous cooling transformation curves of Zr- and Pd-based alloys are calculated and the results are in good agreement with the experimental values. It is suggested that the method can be used to evaluate glass forming ability of alloy systems more effectively. In addition, the calculation results show that the main factors effecting the critical cooling rate are the viscosity of melt, nucleation barrier and critical volume fraction of the crystal, the critical cooling rate is reduced with the increase of the viscosity, nucleation barrier and critical volume fraction of crystal.
