- Abstract
We investigated coercivity, total losses and complex permeability of sintered Fe-Co powder cores to detect magnetization processes performing in ac magnetic field. The Fe-Co solid solution alloy powders with 50:50 wt% ratio were prepared by 1, 15, and 20 h alloyed mixture of pure chemical elements in planetary ball mill. The resulting powder was subsequently sintered into a disk form. The compaction was performed at a pressure of 800 MPa for 5 min at temperatures of 400 °C, 500 °C and 600 °C in vacuum oxidation protective atmosphere, with pressure of 5×10-3 Pa. The best magnetic properties exhibit sample prepared from 1 h alloyed powder, compacted at 600 °C.
