The Future of Waste NdFeB Rare Earth Permanent Magnets and their Role in a Circular Economy
EQUINOX project aims to producte Fe-Al based intermetallic materials that will be non-brittle at low to medium temperatures. A radical new, near net-shape production route is being studied that brings together intermetallic metallurgy and the Kochanek process. These unique intermetallic materials will be used for the production of demonstrators, like brake disks, excavator bumpers, piping elements for liquid rocket engines and cell stack end cones. A strategic target for the EQUINOX (CRM)-free intermetallic materials is to substitute stainless steel parts in high volume end consumer market. EQUINOX’s ambition is to reduce Europe’s dependency in CRMs, since stainless steel contains an average amount of 18% in Cr. EQUINOX has the potential to aid Europe fulfill its policy and strategy of raw materials. Until now, the most promising results were obtained by infiltrating iron samples having 45% porosity with liquid Al. These samples were produced by the Selective Laser Melting method. Another manufacturing route that has proved successful is a modification of Metal Injection Molding, which will be utilized for the production of all but one EQUINOX demonstrators. In both cases, pressure-assisted infiltration revealed regions of effective reaction between Al and Fe.
