We hereby present a simple process, called in situ two-end diffusion (TED), to reach coercivity enhancement with almost unchanged energy product for hot deformed (HD) NdFeB magnets. Coercivity of the HD magnets is increased from 15.1 to 18.7 kOe for

Traditional NdFeB sintered magnets with coercivity larger than 20 kOe, called super-high (SH) level, usually contains considerable amount of high-cost heavy rare earth (HRE), such as Dy or Tb. In this work, high coercivity of 21.4 kOe, which correspo

Directional growth effect on magneto-mechanical properties of Fe81Al19 alloy is studied. The ideal model of heat flux for directional solidification (DS) technique is proposed, and the tuned A/L (the ratio of cross-sectional area and length for the i

Significant enhancement in coercivity for hot deformed (HD) NdFeB magnets is achieved by doping R80Al20 (R= La, Ce, Dy, Tb) alloy powders. All studied samples exhibit fine microstructure with good (00L) texture. By doping R80Al20 powders, the coerciv

Coercivity enhancement of the sintered NdFeB magnets by grain boundary diffusion (GBD) with Tb70Cu30 powders prepared by different milling methods has been compared. The commercial NdFeB sintered magnets with the magnetic properties of Br=14.0 kG, iH

A significant coercivity enhancement of the commercial NdFeB magnets with the magnetic properties of (BH)max = 48.4 MGOe and iHc = 17.5 kOe through grain boundary diffusion (GBD) with low-melting Tb55R20Cu25 alloys is demonstrated. Adopting Tb55R20Cu
