| Abstract Scope |
Nanostructured metallic alloys often exhibit low thermal stability due to the high density of interfaces, which restricts their engineering applicability. Developing and understanding novel stable nanostructured interfaces is crucial, particularly in applications where materials are subjected to extreme environments, such as irradiation resistance coatings. In this study, nanometallic multilayers (NMMs) consisting of crystalline and amorphous Fe-W phases were used to investigate how interfaces influence thermal stability and layer breakdown on the nanoscale. Multilayer and monolithic coatings were synthesized via magnetron co-sputtering and heat-treated up to 750°C. Microstructural transitions and phase evolution within each film were characterized, and it was observed to drive devitrification processes in both monolithic and multilayer films. Differences in microstructural transformation processes could be attributed to the characteristics of crystalline-amorphous or crystalline-crystalline interfaces. |
