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 μ_e of 59.3, a DC-bias performance of 65.6% at a DC magnetic field strength of 100 Oe, and a P_cv 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 μ_e by 91% and a significant reduction in P_cv 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.

添加铁镍粉末改善铁硅铜铌纳米晶粉芯的软磁特性

将不同重量比的铁硅铜铌纳米结晶粉末与铁镍混合，通过冷压制成环形粉末磁芯。研究人员仔细研究了铁镍粉末含量对粉末磁芯软磁性能的影响，并得出了有意义的发现。当铁镍比例为 50 wt.% 时，粉末磁芯的性能达到最佳，μe 为 59.3，在直流磁场强度为 100 Oe 时，直流偏压性能为 65.6%，在 50 mT 条件下，100 kHz 时的 Pcv 为 99.8 kW/m3。与未添加铁镍的粉末磁芯相比，μe 显著提高了 91%，Pcv 显著降低了 45.4%。这种改善可归因于 FeNi 作为空隙填充颗粒的作用，它有效地增强了纳米晶 FeSiBCuNb 粉芯的软磁特性。

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.
