摘　　要：采用分子动力学模拟的方法,研究了CuZr二元非晶在过冷态的结构变化,发现CuZr合金中五重对称性占据了液态结构的主导地位,随着温度的变化,CuZr合金的液态结构表现出很强的结构稳定性,这样的结构稳定性是与CuZr非晶强的非晶形成能力相对应的.Molecular dynamics simulation is used to studing the liquid structure in CuZr bulk metallic glass in supercooled liquid. The fivefold symmetry order dominates in liquid are found, and the CuZr structure shows high structure resistance to the variation of the temperature. The high structure stability is in consistent with the high glass forming ability of CuZr metallic glass.
