摘要 运用蒙特卡罗方法计算模拟了Al-Mg-Si-Zn合金时效初期微结构的演化过程。模拟结果表明:Al-Mg-Si-Zn合金中Si在早期延缓了Mg/Zn形成复合团簇的进程速度,降低了Al-Mg-Si-Zn合金中Mg、Zn原子结合的程度,但未能显著改变Al-Mg-Si-Zn合金时效早期Zn/Mg团簇的演化过程,这可能是由Si原子与Mg、Zn原子之间相互作用都较弱造成的。研究表明,空位在微结构演化过程中对形成原子偏聚团起到重要作用。 Monte-Carlo method was applied to simulate the micro-structural evolution of Al-Mg-Si-Zn alloy.The simulation results showed that Si atoms tend to depress Mg atoms to form Mg-Zn segregation,which is owing to the weak interaction of Si atoms with Mg and Zn atoms.The vacancies in alloy play an important role in formation of clusters during microstructural evolution of Al-Mg-Si-Zn alloy.
