Abstract :
The magnetic properties of Sm2(Co,Fe,Cu,Zr)17 magnets were improved by increasing the Fe content without raising the Zr content. With increasing Fe content, the remanence rises monotonically while the intrinsic coercive force drops sharply for 0.27<v<0.29 and then increases for 0.30<v<0.33 in Sm(CobalFevCu0.056Zr0.02) 7.546. For the nominal composition Sm(Co0.612Fe 0.316Cu0.052Zr0.02)7.73, most magnets developed (BH)max=31-33 MGOe while some reached 33-34 MGOe. Still higher Fe contents may result in further improvement of Sm2TM17 magnets
