Magnetic Materials TRIZ Cases
- Rare Earth Magnet Composition Optimizing Br and HcJ
Precise control of B, Cu, and O contents suppresses soft R2T17 phase formation while maintaining high residual flux density.
- Laminated Amorphous Alloy Ribbon Laser Marking for Low Iron Loss
Merging laser scribing with ribbon lamination resolves the trade-off between low iron loss and production efficiency in transformer core manufacturing.
- Superconducting Levitation Surface Tape Configuration
Butt-jointed planar superconducting tapes arranged in orthogonal layers resolve flux pinning instability at tape edges.
- R-Fe-B Sintered Magnet Core/Shell Structure for High Coercivity
A R-Fe-B sintered magnet forms a core/shell structure with an HR-rich grain boundary layer to enhance magnetic coercivity.
- Permanent Magnet Manufacturing via Binder-Derived Ceramic Matrix
Binder-derived ceramic matrix embeds magnetic particles, preventing crystal growth and eliminating pyrophoricity risks during sintering.
- Co-Ni Alloy Crystal Texture Control via Heat Treatment
Heat treatment at 500-800°C normalizes crystal texture in a Co-Ni-based alloy, resolving the trade-off between mechanical strength and workability.
