Effect of doping Al-Cu-Fe alloy on the microstructure and magnetic properties of annealed Nd-Fe-Co-B ribbons
2022, Physica B: Condensed MatterCitation Excerpt :Chang et al. [10] annealed Nd8YFe72Ti2Zr2B15 ribbons and found that the appropriate annealing treatment significantly improved the squareness of the demagnetization curves. In addition, many attempts have been made to modify the chemical composition, optimize the microstructure, and change the crystallization mechanism by adding Co, Cu, Ga, Al, or Nb into Nd-Fe-B magnets [11–16]. A small amount of low-melting-point elements such as Cu, Al, or Ga must be added to the Nd-Fe-B alloy to optimize the annealing effect [17–21].

2017, Journal of Magnetism and Magnetic MaterialsCitation Excerpt :It was reported that the coercivity mechanism of the melt-spun Nd-Fe-B alloys is the pinning of magnetic domain walls by grain boundary phases [17–20]. Many researchers have attempted to modify the grain boundary phase by additives such as Cu, Ga, Al and Nb [20–25]. Nb shows a low solubility in Nd2Fe14B [26] and α-Fe [27], and it is substantially segregated on the grain boundaries precipitated as NbFeB boride [23] or amorphous phase [28], which served as crystal growth inhibitor to refine the grain microstructure.
