| Abstract Scope |
Interfaces introduced in a structure act to influence the diffusion of solute atoms within that structure. In this work, a novel heterointerface between Fe8Cr and Fe2O3 is synthesized such that a network of misfit dislocations develops across the semi-coherent interface. This interface is synthesized by PVD sputtering a layered structure of a single-crystal, body-centered cubic Fe8Cr layer and a polycrystalline, rhombohedral Fe2O3 layer. This Fe8Cr-Fe2O3 thin film is then subjected to heavy Fe ion irradiation at 5.0 MeV and 250 oC. High-resolution electron microscopy is used to characterize the misfit dislocation network across the semi-coherent interface formed by the two materials with a misfit strain of 1.2 percent and to understand the material response under irradiation environments. |
