Abstract
Isotropic NdFeB powders were blended with pure Zn and Sn powders by planetary ball milling. The mixed powders were compacted by the current applied pressing (CA-press) process and subsequently deformed by the current applied deformation (CA-deformation) process. The coercivity of CA-pressed magnets was nearly the same regardless of milling time; however, the coercivity of CA-deformed magnets decreased with an increase of milling time. The addition of Zn or Sn at less than 1 wt% resulted in an increase of coercivity and anti-corrosion properties of the CA-pressed isotropic magnets and CA-deformed anisotropic magnets. CA-deformed NdFeB magnets with 0.3 wt% Zn or Sn addition consisted of smaller grains and showed about 80% higher coercivity than additive-free magnets.
