辐照后基体中的缺陷不断产生、迁移和团聚,形成团簇、位错、位错环、空洞和析出相等更大尺度缺陷。点缺陷的产生以及平衡浓度可以通过其形成能反映。计算了不同尺寸团簇的形成能变化。
After irradiation, defects in the matrix continue to generate, migrate and agglomerate, forming clusters, dislocations, dislocation rings, voids and precipitates of the same larger scale defects. The production of point defects and the equilibrium concentration can be reflected by their formation. The formation energy variation of clusters with different sizes is calculated.
