采用镶嵌原子势(EAM)和分子动力学方法模拟了纯Al的液态,过冷液态和非晶态的微观结构采用键取向序和对分析方法考察了结构和结构转变的特征

EAM together with MD has been applied to the investigation of rapid solidification process of pure Al. The structures of pure Al in liquid state, supercoolled liquid state and noncrystalline. The evaluation of structures have been examined by using bond o
