Abstract
Hydrogen decrepitation as a highly efficient and excellent crushing method is widely used in the preparation of NdFeB magnets. However, this method still exist many difficulties in the industrial preparation for 2:17 type SmCo alloys owing to high hydrogen pressure. Our previous work has reported 2:17 type SmCo alloys occur HD at room temperature and hydrogen pressure of 0.3 MPa and has shown that Fe atom improved hydrogenation decrepitation ability of alloys by improving hydrogen-absorbing ability of 1:7 phase. But the mechanism that Fe improve hydrogen-absorbing ability of the 1:7 phase still need further study. In addition, subsequent degassing behaviour of alloys have been studied by using DSC.
