| Abstract Scope |
The production of permanent magnets predominantly relies on rare earth elements (REEs), which present environmental challenges, supply chain instability, high costs, and recycling difficulties. This research aims to develop sustainable REE-free permanent magnets (PMs) for energy and mobility applications, focusing on innovative compositions of AlNiCo and high entropy alloys (HEAs) processed via additive manufacturing (AM). Recycling strategies will emphasize environmentally friendly repurposing, particularly cobalt (Co) recovery. The new PMs target a maximum energy product ((BH)max) of ≥60 kJ/m³ for Co content ≤24% and (BH)max of ≥72 kJ/m³ for Co content ≤35%. The research uses open-source modeling tools and machine learning to expedite the development of environmentally benign materials suitable for AM. This approach leverages AM's ability to create complex shapes and engineer microstructures, aiming to develop anisotropic microstructures with enhanced coercivity and desired energy products, towards an improved industrial competitiveness and sustainability. |
