| Abstract Scope |
Complex Concentrated Alloys (CCAs) provide exciting opportunities to explore the complex relationship between processing, structure, properties, and compositional space. For FeNiMoW, experimentally it has been observed that the FCC phase contains equal amounts of Fe and Ni with approximately 20% of the refractory alloys. Modeling the FCC matrix as a solid solution using DFT-based calculations have demonstrated a lack of stability, but modeling said matrix like tetrataenite – an L10 FeNi mineral found in meteorites- it becomes more stable and shown increased magnetic properties. Interest in tetrataenite and similar alloys has been of recent interest due to its magnetic properties rivalling rare earth element magnets, but tetrataenite takes millions of years to form naturally. In this study, we will explore the phase stability of FeNiMoW-based alloys with specific attention on fabricating a L10-like structure similar to FeNi with promising magnetic properties. |
