Effect of gallium additions on the magnetic properties of die-upset forged Fe-Nd-B type melt spun alloys

Effect of Nd content on the microstructure and coercivity of hot-deformed Nd–Fe–B permanent magnets

“…4d and 5d) shows the same distribution behavior as that of Nd. Ga has been reported to be an effective additive to enhance the coercivity due to the better isolation of the hard magnetic grains and the pinning effect of the Ga-rich phase [26][27][28]. Fig.…”

Processing of high-performance anisotropic permanent magnets by die-upset forging

“…1c). Addition of gallium, which does not dissolve in the hard magnetic phase, contributes to the amount of the ternary eutectic [14].…”
