In this paper,the forming mechanism and affecting favtor of bulk metallic glasses is systematically discussed from the aspects of thermodynamic, kinetic and microstructure . Thermodynamic factors which favor the amorphization of alloys analyzed, the glass forming range of ternary alloys system was proposed by using Miedema theory, Toop model and considering the influence of free energy of pure metals at different temperature. The approach was applied to predict the composition range of amorphous Mg-Cu-La alloys. Several methods(such as three empirical criterions ,binary alloys phase diagram , Miedema theory and Toop mode) were used to design a series of Mg65Cu25La10 、Mg68Cu17La15 and Mg57Cu23La20 alloys, These bulk amorphous alloys with maximum diameter thickness reaching to 1mm were prepared by means of graphite-molding casting though the raw materials are of a low purity by conventional casting processes at a low cooling rate.
