| Abstract: | Sm2(Co,Fe,Cu,Zr)17 magnet material was prepared by powder metallurgy process. The oxygenation of sduring the process and its influence on the microstructure and magnetic properties were investigated. The micro-analysis indicates that the oxygenation hole of Sm in the form of Sm2O3 destroys the microstructure of the material, as a result, degrades the magnetic properties. |
