摘要
To investigate the effect of adding microfiber glass on the magnetic and mechanic properties of anisotropic Nd-Fe-B magnets, the Nd-Fe-B magnets with epoxy resin lubricant were prepared by calendering and magnetic alignment steps with heating. The effect of heating during magnetic alignment process on magnetic and mechanic properties of the prepared Nd-Fe-B magnets was investigated and optimized. As a result, heating unaligned flexible bonded magnets to 100 °C for 30 min during magnetic alignment resulted in the largest (BH)_(max), which increased to over 61.5% with DOA increasing and to over 38% compared with unaligned Nd-Fe-B magnets prepared by one step method.
