The powder was sintered using the ultra-fast current aided method. It turned out that too long discharge time leads to appearing of a soft magnetic phase and simultaneously, decrease in coercivity of the compacted powder. Nevertheless, it was possible to establish preference technology parameters, preserving magnetic hardness of the alloy. As a final test, an impact of Co-powder addition on magnetic properties was studied. The introduced soft magnetic phase (about 20 wt. %) caused about 30% increase of magnetic remanence, which is a result of direct exchange interactions between the two phases.}, type={Artykuły / Articles}, title={Ultra-Fast Current Aided Sintering of High Coercive Magnetic Powders and Composites}, URL={http://www.czasopisma.pan.pl/Content/111355/PDF/AMM-2019-2-58-Granek.pdf}, doi={10.24425/amm.2019.127615}, keywords={magnetic composites, ultra-fast current sintering, high coercive alloys}, }
