| Abstract Scope |
The quest for high-performance, rare-earth-free permanent magnets has recently experienced a significant surge in interest, driven by both economic and environmental considerations. Among the most promising candidates, Alnico alloys stand out due to their excellent magnetic properties. However, a major hurdle limiting their widespread adoption is their inherent brittleness. The unique magnetic characteristics of Alnico originate from a meticulously controlled nano-scale spinodal decomposition of BCC matrix into Fe-Co-rich (α1) phase and a Ni-Al-Ti-rich (α2) phase. Recent research has shed light on the mechanical disparity between these phases, revealing that the α1 phase exhibits ductility, while the α2 (L21) is exceptionally brittle, exacerbated by the presence of Al. Conversely, L12 type α2-phase would possess desirable ductile properties. Recognizing this, the current study delves into the fascinating interplay between mechanical and magnetic properties in a Co-Fe-Ni-Ti-Cu chemically complex concentrated alloy through thermokinetically controlled fabrication by LDED-based AM process, followed by thermal treatments. |
