| 中文摘要 | The intrinsic coercivities H(c) of Nd14Dy(x)Fe79-(x)B7 magnets, prepared by a powder metallurgical method, with an addition of Dy(x = 2 at. %), reached 21 kOe. The intrinsic coercivity H(c) was kept over 10 kOe when the heating temperature was 150-degrees-C and the temperature coefficient alpha(H(c)) = - 0.35%/degrees-C was in a temperature range of 16-150-degrees-C. After aging at 120-degrees-C for 400 h, the intrinsic coercivities H(c) and magnetic energy products (BH)max of the magnets did not change as usual, remaining at H(c) = 21 kOe and (BH)(max) = 30 MGOe. The NdFeB magnets with all kinds of the intrinsic coercivities were compared at various temperatures also. The experimental results show that high-temperature features of the NdFeB magnets were improved by increasing the intrinsic coercivity. |
