Rare earth permanent magnets Sm2(Co, Fe, Cu, Zr)17 for high temperature applications
چکیده انگلیسی

Sintered Sm(CobalFexCu0.1Zr0.03)7.5 (x=0.09–0.21) permanent magnets with higher Fe content were found to have higher remanence Br and maximum energy product (BH)max at room temperature. Br and (BH)max reached maximum of 0.96 T and 176.7 kJ/m3, respectively at room temperature when the Fe content x reached 0.21. However, the intrinsic coercivity Hci at room temperature increased gradually when the Fe content x increased from 0.09 to 0.15, but when x further increased to 0.21, Hci decreased. Hci attained its peak value of 2276.6 kA/m with Fe content x=0.15 at room temperature. For magnets with x=0.15, Br, (BH)max and Hci reached 0.67 T, 81.2 kJ/m3 and 509.4 kA/m at 500 °C, respectively, showing good high temperature stability, which could be used in high temperature applications.
