| Abstract Scope |
Permanent magnets are engineered for maximum energy product, but brittleness and low toughness restrict their use in load-bearing, damage-tolerant systems. Metal-matrix magnetic composites (MMMCs) expand the design space by embedding hard-magnetic phases within ductile metals, enabling concurrent magnetic function and structural reliability. The central challenge is balancing magnetic phase fraction with manufacturability and interface integrity: increasing reinforcement boosts volumetric performance yet promotes cracking, particle damage, and adverse interfacial reactions that degrade coercivity and toughness. We present a solid-state, low-thermal-budget processing strategy that uses intense plastic deformation to refine and disperse the magnetic phase and to form controlled nanoscale interphases that promote metallurgical bonding without demagnetization. Structure–property correlations show that engineered interfaces and hierarchical microstructures can raise strength while preserving deformation capacity and a robust hard-magnetic response, establishing practical design rules for scalable multifunctional components in energy, transportation, and defense. |
