To ensure that the material has ferromagnetic properties, two different routes were taken to produce τ-MnAlC phase powder. METALPINE's task in this project is to atomise the MnAlC material to obtain powder with a crystallographic structure based on the ε-phase (precursor). Subsequent heat treatment and investigations by IMDEA revealed successful transformation to almost pure τ-MnAlC phase. LCM produced the MnAlC alloy by casting, which was subsequently crushed and thus processed into powder. After initial difficulties with comminution of cast ingots, IMDEA have developed a ball milling method based on IMDEA’s self-developed “flash-milling”, that makes it possible to produce powders with a size of less than 300μm. A subsequent heat treatment influences the magnetic properties of the material, so the aim is to find a compromise between milling time and annealing time to achieve the highest possible remanence and coercivity (considering that typically for permanent magnets the increase in one of these properties is accompanied by a decrease in the second one). MBN applied its HEBM technology to replicate the “flash-milling” effect at pilot scale, towards a process industrialization. the target value for this deliverable for the remanence was achieved when starting from τ-phase synthesis, while the value of the coercivity is approx. 3% lower than target. When starting from ε-phase synthesis, approx. 90% of target values have been achieved. The sample with the best magnetic properties so far was selected to aim for larger scale production and to further optimise the annealing process. MnAlC τ-phase powder material has been already obtained from scale-up activities and delivered for initial magnet manufacturing tests to WP2 partners.
