摘要
采用分子动力学方法对液态Ａｌ的凝固过程中的微观结构转变特性进行了模拟研究．发现在凝固过程中以１５５１键型数目的变化最为显著．模拟结果表明：随着温度降低，系统有序度增加，无序度下降。
A simulation study on the transition properties of microstructures during solidification of liquid metal Al has been performed by the molecular dynamics method. It has been found that the number of 1551 bonds changed remarkably during solidification. It is demonstrated that with the decrease of temperature, the degree of order of system is increased, while the degree of disorder of the system is decreased.
