Abstract
A new method is described which produces fully dense, well‐aligned Nd‐Fe‐B magnets from rapidly quenched ribbons. Full density is achieved by hot pressing at ∼15 kpsi in argon at 700 °C. A second hot press in a larger die cavity to allow deformation transverse to the press direction (die upsetting) introduces a preferred magnetization direction parallel to the press direction. Energy products of 40 MGOe (Br/Hci=13.5 kG/11 kOe) have been generated by this method.Keywords
