Simultaneous addition of (Re, W, Zr), (Al, Cr) or (Al, Cr, Nb) to the sintered (Nd, Dy)–(Fe, Co)–B magnets affects: refinement of microstructure, high coercivity, thermal stability and improving intrinsic corrosion resistance. This is due to the replacing of conventional Nd–rich constituents by Nd–Co and formation $M$–(Fe, Co), $M$–(Fe, Co)–B ($M$ = Cr, Nb, W, Zr) phases along and/or within the grains. The adding elements strongly influence coercivity mechanism.
