点缺陷及其团簇形成能的大小反映了缺陷聚合成更大尺寸缺陷的速度。对比了空位与间隙原子在FeCrAl中的不同扩散行为,计算了扩散系数和迁移能。
The size of point defect and its cluster formation energy reflects the speed of defect aggregation into larger size defect. The diffusion behaviors of vacancy atoms and interstitial atoms in FeCrAl are compared, and the diffusion coefficients and migration energies are calculated.
