以单辊法制备的(Pr,Dy)<inf>15</inf> (Fe,Co)<inf>77</inf> (B，C)<inf>8</inf>合金熔纺带为研究对象，研究了Pr<inf>15</inf>Fe<inf>77</inf>B<inf>8</inf>合金中C取代B、Co取代Fe、Dy取代Pr，以及基体表面速度和后续退火对带磁性能的影响。此外，在最佳条件下，用淬火形成的条带制备了粘结磁体。当衬底表面速度为11.8 m/s时，制备的Pr<inf >5 </inf>Fe<inf>77</inf>B<inf>8</inf>能带的最大能量积为98.3 kJ/m<sup>3</sup>。在(Pr,Dy)<inf>15</inf>（Fe,Co)<inf>77</inf>(B，C)<inf>8</inf>）带中，证实(Pr<inf>0.95</inf>Dy<inf>0.05</inf>)<inf>15</inf> （Fe<inf>0.9</inf>Co<inf>0.1</inf>)<inf>77</inf>(B<inf>0.5</inf>C<inf>0.5</inf>)<inf>8</inf>合金中含有Dy和Co以改善B<inf>r</inf>和H<inf>CB</inf>的温度依赖性）获得了最高的能量生长量96.4 kJ/m<sup>3</ inf>。具有最高矫顽力的样品的x射线衍射图显示出非晶态和细晶相的混合物。最好的获得粘结磁体的磁性(公关<正> 0.95 < /正> Dy <正> < / inf > 0.05) <正> 15 < /正> (Fe <正> 0.9 < /正>有限公司<正> < / inf > 0.1) <正> 77 < /正> (B <正> 0.5 < /正> C <正> < / inf > 0.5) <正> 8 < / inf > (BH) <正> max < /正> = 64.9 kJ / m <一口> 3 < / >一同晚餐,H <正> CJ / <正> = 1400 kA / m H <正> CB / <正> = 419 kA / m和B <正> r < /正> = 0.62 t的温度依赖性发现B <正> H r < / inf >和<正> CB / <正>(公关、Dy)——(铁、Co)——(B, C)保税磁铁优于Pr-Fe-B粘结磁体。
Focusing on melt-spun ribbons of (Pr,Dy)<inf>15</inf> (Fe,Co)<inf>77</inf> (B,C)<inf>8</inf> alloys prepared by the single roller method, the authors studied the effects of C substitution for B, Co for Fe and Dy for Pr in Pr<inf>15</inf>Fe<inf>77</inf>B<inf>8</inf> alloy, and of the substrate surface velocity and subsequent annealing, on the ribbon magnetic properties. In addition, bonded magnets were fabricated from ribbons formed by quenching under optimum conditions. The maximum energy product of 98.3 kJ/m<sup>3</sup> was obtained for Pr<inf>15</inf>Fe<inf>77</inf>B<inf>8</inf> ribbon prepared at a substrate surface velocity of 11.8 m/s. In (Pr,Dy)<inf>15</inf>(Fe,Co)<inf>77</inf>(B,C)<inf>8</inf> ribbons, it was confirmed that the highest maximum energy product, 96.4 kJ/m<sup>3</sup>, was obtained for (Pr<inf>0.95</inf>Dy<inf>0.05</inf>)<inf>15</inf> (Fe<inf>0.9</inf>Co<inf>0.1</inf>)<inf>77</inf>(B<inf>0.5</inf>C<inf>0.5</inf>)<inf>8</inf> alloy, which contains Dy and Co to improve the temperature dependence of B<inf>r</inf> and H<inf>CB</inf>. X-ray diffraction patterns from samples with the highest coercivity showed a mixture of an amorphous and a fine crystalline phase. The best magnetic properties obtained in bonded magnets of (Pr<inf>0.95</inf>Dy<inf>0.05</inf>) <inf>15</inf>(Fe<inf>0.9</inf>Co<inf>0.1</inf>)<inf>77</inf>(B<inf>0.5</inf>C<inf>0.5</inf>)<inf>8</inf> were (BH)<inf>max</inf>=64.9 kJ/m<sup>3</sup>, H<inf>CJ</inf>=1400 kA/m, H<inf>CB</inf>=419 kA/m, and B<inf>r</inf>=0.62 T. It was found that the temperature dependences of the B<inf>r</inf> and H<inf>CB</inf> of (Pr,Dy)-(Fe,Co)-(B,C) bonded magnets are superior to those of Pr-Fe-B bonded magnets.
