Conversion between movement and electricity has become a critical part of the global renewable energy system, with wind mills and electric vehicles as prominent examples. Soft magnetic materials are in the heart of electromagnetic generators and electric motors, but there is still much to desire from their functional and mechanical properties. Non-ideal magnetic properties may lead to fatigue and loss of generation efficiency or even mechanical failure. The present project aims to introduce a new generation of materials for soft magnets: high entropy alloys (HEA) generated with additive manufacturing (AM). HEA have demonstrated surprising combinations of properties in various fields, and a few recent works have indicated that this may also be the case for soft magnetic materials. Furthermore, the rich compositional freedom in these materials implies huge possibilities of tailoring functional and mechanical properties to specific applications. The goal of Magnificent is to identify novel HEA-based soft magnets with superior magnetic properties that exhibit significantly reduced losses and fatigue compared to the current state-of-the-art. At the same time, processing by AM facilitates net shape construction of complex geometries and potentially low-emission, distributed production. The project constitutes a complete suite of synthesis and characterization tools, facilitating screening of a large number of potential candidate materials in the search of optimal compositions. In addition, modelling efforts will contribute to the screening by suggesting new materials as well as rationalizing experimental results. But first and foremost, the project partners have endorsed the principles of responsible research and innovation, with specific actions on health, environment, and safety, proactive ethical principles, and a comprehensive risk assessment.
