摘要
文章采用多体势，用分子动力学模拟研究了含有无序界面的Ｎｉ／Ｚｒ双层膜在等温退火下的自发非晶化过程．在原子尺度上首次观察到了Ｎｉ－Ｚｒ之间的互扩散和合金化，以及由此导致的从界面开始、由扩散控制的非晶化．
On the basis of an n-body potential,a molecular-dynamics simulation for a Ni/Zr bilayer with a preset disordered interfacial layer was performed to investigate the vitrification process upon isothermal annealing at medium temperatures.Mutual diffusion and alloying between Ni and Zr layers were observed for the first time,which in turn resulted in a diffusion-controlled vitrification initiating from the interface.
