| Abstract Scope |
The shortage of raw materials required for the development of advanced magnetic materials for energy applications drives the search of new alloys with reduced content of critical elements and performance similar to the current ones. Recent progress in magnetocaloric materials for solid-state refrigeration and high-energy permanent magnets open new opportunities to explore future technological developments in additive manufacturing. Metamagnetic shape memory alloys are promising candidates for magnetic refrigeration due to their high entropy change around the first-order martensitic transformation but their crystalline phase is unstable at high temperatures (>300ºC). Novel nitride ThMn12-based permanent magnets are good option to replace the conventional Nd-Fe-B magnet. Nd(Fe,Mo)12Nx showed high performance but they can degrade at temperatures above 400ºC when Nitrogen starts to leave the interstitial sites of the ThMn12-type structure. Different inks and filaments were developed to study the best parameters in the fabrication of complex structured materials by screen- and 3D-printing. |
