Abstract
FeSiBCuNb nanocrystalline powder was mixed with FeNi at varying weight ratios to fabricate toroidal powder cores through cold pressing. The effect of FeNi powder content on the soft magnetic properties of the powder cores was meticulously investigated, leading to a meaningful discovery. The optimal performance was achieved when the FeNi ratio is 50 wt.%, with a μe of 59.3, a DC-bias performance of 65.6% at a DC magnetic field strength of 100 Oe, and a Pcv of 99.8 kW/m3 at 100 kHz under 50 mT conditions. Compared to the powder cores without FeNi addition, there was a remarkable improvement in μe by 91% and a significant reduction in Pcv by 45.4%. This improvement can be attributed to the role of FeNi as void-filling particles, which effectively enhance the soft magnetic properties of the nanocrystalline FeSiBCuNb powder cores.
期刊介绍:
The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid.
In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
