摘要：

The relationships of the magnetic properties of the hydrogenated permanent magnetic material NdFeB with the hydrogenation temperature and time, as well as the dehydrogenation temperature and time, are discussed in detail. The NdFeB alloy was melted in a vacuum mid-frequency induction furnace and then homogenized. The hydrogenation of the alloy and the dehydrogenation of the hydride were conducted in a vacuum / hydrogen at mosphere furnace. The experimental results show that the permanent magnetic material, which is hydrogenized at 770 degrees% for 2 h and dehydrogenized under the hydrogen pressure of less than 10(-2) Pa at 730 degrees C, has an excellent magnetic property.
