Magnetic Materials TRIZ Cases
- Nd5Fe17 Rare-Earth Magnet Grain Boundary Optimization
Nd5Fe17 magnet grain boundary phase concentrates rare earth elements to isolate low coercivity sub-phases and boost overall coercivity.
- R-T-B Sintered Magnet Heavy Rare-Earth Diffusion Process
A sintered R-T-B magnet undergoes heavy rare-earth diffusion from a fluoride or oxide source during relative motion heating.
- ThMn12 Magnetic Material Dual-Phase Structure for Coercive Force
A ThMn12 magnetic material with a dual-phase structure enhances coercive force and saturation magnetization, resolving the trade-off between these parameters.
- R-T-B Permanent Magnet Voids Pin Domain Walls
Voids in the grain boundary phase of R-T-B magnets suppress domain wall movement, increasing coercivity without reducing residual flux density.
- Hot Deformed Magnet Grain Refinement via Nb Ta Segregation
Hot deformed magnets eliminate coarse equiaxed grains by adding Nb or Ta to segregate at grain boundaries, boosting remanence to 1.54 T.
- Rare Earth Magnet Microstructure for High-Temperature Coercivity
R2T14B crystal grains contain fine products that pin magnetic domain walls to enhance coercivity.
