Effect of Pr-Ga dual-alloys diffusion on magnetic properties and thermal stability of hot-deformed PrNd-Fe-B magnets
文献摘要:
To investigate the influence of the addition of Pr-Ga alloys on magnetic properties and morphology of materials,the hot-deformed PrNd-Fe-B magnets were prepared by the addition of Pr-Ga alloys using a dual-alloys diffusion.The room-temperature coercivity of the hot-deformed PrNd-Fe-B magnets in-creases substantially from 1.68 to 2.34 T,while the remanence decreases from 1.42 to 1.24 T,by the addition of 5 wt% Pr-Ga alloys.Moreover,the thermal stability of coercivity improves from-0.46%/℃to-0.42%/℃.Two types of grain boundary phases (PrNd-rich and PrNd-Ga-rich) are generated at grain boundaries by microstructural analysis,resulting in the decrease of Fe element concentration from more than 60% to about 10% at grain boundaries.The decrease of ferromagnetic element concentration at grain boundaries and the refinement of grain are considered to be the main reasons for the improvement of coercivity and thermal stability.
