Magnetic Materials TRIZ Cases
- Curie-Point Magnetization With Isotropic SmCo for Uniform Flux
Heating above the Curie point and cooling under isotropic SmCo fields improves multipolar magnetization uniformity for sensors and encoders.
- R-Fe-B Magnetic Composition for High-Temperature Magnetization Retention
Co and Ni substitution in La-reduced R-Fe-B magnets helps preserve high-temperature saturation magnetization while lowering Nd usage.
- Low-B R-Fe-B Sintered Magnet Grain Boundary Phase for Higher Hcj
Controlled Ga-Cu-Ti grain boundary phases raise Hcj and Br in low-B R-Fe-B sintered magnets while reducing Dy and Tb dependence.
- R-T-B Sintered Magnet Composition for High Br and Thermal Coercivity
Sn- and C-enabled grain boundary phases help R-T-B sintered magnets keep high Br and coercivity at elevated temperature without Dy or Tb.
- Rare Earth Magnet Sintering With Dual-Size SmFeN and Zinc Binder
Pressure sintering with dual-size SmFeN powder and zinc binder shortens densification time while limiting decomposition and preserving magnetization.
- Sintered R-T-B Magnet Composition for Br and ET Coercivity Stability
A grain boundary with R-T-(M1, M2) and R-M2-C phases uses Sn and C to raise Br and ET stability without sacrificing RT coercivity.
- Cerium-Cobalt Magnet Composition for High Anisotropy
Zirconium-doped cerium iron cobalt alloys raise magnetic anisotropy while preserving magnetic moment, reducing reliance on scarce rare-earths.
