摘要：
The structure and magnetic properties of rapidly hardened powders from alloys based on Nd2Fe14B compounds are studied. Centrifugally sprayed powders with a multiphase structure bearing Nd2Fe14B, Nd(OH)(3), and alpha-Fe phases are described. A decrease in the size of crystals of the magnetic phases (Nd2Fe14B and alpha-Fe) and the amount of alpha-Fe are shown to increase the magnetic properties of such powders. At the same time, powders obtained by melt spinning are shown to be single-phase ones with more dispersed crystals and higher magnetic properties.
