Effect of the substitution of Pr for Nd on microstructure and magnetic properties of nanocomposite Nd2Fe14B/α-Fe magnets
Description
Microstructure and magnetic properties of melt-spun nanocomposite magnets with nominal compositions of (Nd1-xPrx)9Fe86B5 (x=0-1) were investigated. Substitution of Nd by Pr could significantly improve the hard magnetic properties of the nanocomposite magnets; the intrinsic coercivity (iHc) and the maximum magnetic energy product ((BH)max) increase from 414 kA/m and 124 kJ/m3 for x=0 to 493 kA/m and 152 kJ/m3 for x=0.6, respectively. Further substituting Nd by Pr (x>0.6) strongly weakens exchange-coupling interaction between magnetically hard and soft phases
