Popis:	The magnetic and mechanical properties of the magnets Fe-Nd-B system are more dependent on the size and shape of the grain structure. The authors explored the effect of the neodymium content and the addition of transition metals (Mo, Co, Al) and rare-earth metals (Dy, Tb) on the formation of the structure alloy gas atomization powder the Fe-Nd-B system. It has been shown that doping enhances the formation of grain blocks with a radial gradient in the direction of grain growth. The alloying of a gas atomization powder alloy of the Fe-Nd-B system with rare-earth metals increases the anisotropy of the grain shape.
