Description
Summary:Simultaneous Co and Cu additions to sintered NdDyFeB magnets refine the microstructure and improve the energy density. This is due to the replacement of the conventional Nd-rich constituents by RE-(Co,Cu) phases with low melting points, such as RECu or RE3Co. A remanence of 1.41 T and an energy density of 383 kJ/m3 could be achieved.
