从原子论的观点出发，结合液体的脆性，讨论了大块非晶合金的合金选择问题。通过将玻璃形成的拓扑理论推广到多组元体系，提出增加所涉及的元素数目、增大原子尺寸比、增大大小原子间的吸引力以及在小原子间引入排斥势等将有助于大块金属玻璃的形成。
The question of alloy selection for bulk metallic glasses is addressed from the atomistic point of view, in relation to the fragility of liquid. By extending the topological theory of glass formation to multi-component systems, it is suggested that increasing the number of elements involved, increasing the atomic size ratio, increasing the attractive force between small and large atoms, and introducing a repulsive potential between small atoms will help the formation of bulk metallic glasses.
