摘 要: 综述了近年来所发现的表征大块金属玻璃形成能力的参数,其中包括基于动力学、液相稳定性和抗晶化能力、物理结构参数、液相稳定性和原子尺寸结构、价电子浓度和有序相与无序相的竞争.指出了大块金属玻璃形成能力研究的复杂性,以及理论基础的重要性. The latest research parameters on glass-forming ability (GFA) for bulk metallic glasses are summarized. The parameters are based on kinetics, stability of liquid phase and anti-crystallizing ability, physical and chemical parameters, stability of liquid phase and atomic configuration, the valence electron concentration, order-disorder competition, respectively. Finally, it is pointed out that research on GFA for bulk metallic glasses is a complex program. The theories should play important role in studying glassforming ability for bulk metallic glasses.
