| 摘 要： | 将微量杂质对再结晶的阻碍作用转化为再结晶自由能变化，从而建立微量杂质作用下的能量转化模型。采用Monte Carlo方法实现能量转化模型的数值模拟，结果表明，微量杂质元素含量的波动对再结晶晶粒长大的影响很大。并与高纯铝实验结果进行了对比，对比表明模拟结果与实验结果很吻合。

| Abstract: | The influence of trace impurities on the recrystallization was analyzed with the energy conversion model, in which the drag force of impurity atoms is converted into the free energy change during recrystallization. And the energy conversion model is implemented with the Monte Carlo numeric simulation method. The simulated results reveal that the fluctuation of trace impurity has strong influence on the recrystallization behavior. And the simulation results agree with the experimental result well. |
