材料的辐照效应产生于入射粒子与材料点阵原子的相互作用,造成缺陷和微结构的演化,FeCrAl中由于存在Cr和Al,产生不同自间隙原子类型。碰撞级联过程的形貌和产生的缺陷数有所差异。
The irradiation effect of the material is generated by the interaction between the incident particles and the lattice atoms of the material, resulting in the evolution of defects and microstructure. In FeCrAl, different types of self-gap atoms are generated due to the presence of Cr and Al. The morphology and defect number of the collision cascade process are different.
