Soft magnetic materials are widely used as magnetic cores in transformers, motors, and generators as they can be easily magnetized and demagnetized. By using high-speed energy ball milling and spark plasma sintering to synthesise and consolidate Fe-Cu alloys, this project aims to understand the properties of various compositions of Fe-Cu. Characterisation techniques such as Scanning Electron Microscopy, X-ray Diffraction, Energy Dispersive X-ray Spectrometry, Vickers Hardness Test were employed to study the morphology, crystallography, magnetic and mechanical properties of the alloys. It was found that lower Cu content alloys, specifically lesser than 4% Cu, displayed the ferromagnetic nature and are promising for soft magnetic applications. However, this should not rule out the promising applications of the other compositions of Fe-Cu. Further study of the electrical and thermal properties of Fe-Cu alloys should be done to understand this metastable, immiscible system more holistically.
