Nd2Fe17 nanograins effect on the coercivity of HDDR NdFeB magnets with low boron content

Aizhi Sun; Shen Wu; Wenhuan Xu; Jin Wang; Qian Zhang; Fuqiang Zhai; Alex A. Volinsky

Relationships between the coercivity of hydrogenation disproportionation desorption recombination (HDDR) Nd12.5Fe81.5−xCo6Bx bonded magnets and boron content were investigated. Nd2Fe17 phase with planar magnetic anisotropy is present in the microstructure when x= 4at%–5.88at%, which does not reduce the coercivity of the bonded magnets. High-resolution transmission electron microscopy (TEM) images show that Nd2Fe17 phase exists in the form of nanocrystals in the Nd2Fe14B matrix. There is an exchange-coupling interaction between the two phases so that the coercivity of HDDR Nd12.5Fe81.5−xCo6Bx bonded magnets is hardly reduced with a decrease in boron content.

Magnetic properties and loss separation in iron-silicone-MnZn ferrite soft magnetic composites

Shen Wu; Aizhi Sun; Wenhuan Xu; Chao Zou; Jun Yang; Juan Dong

This paper investigates the magnetic and structural properties of iron-based soft magnetic composites coated with silicone-MnZn ferrite hybrid. The organic silicone resin was added to improve the flexibility of the insulated iron powder and causes better adhesion between particles to increase the mechanical properties. Scanning electron microscopy and distribution maps show that the iron particle surface is covered with a thin layer of silicone-MnZn ferrite. Silicone-MnZn ferrite coated samples have higher permeability when compared with the non-magnetic silicone resin coated compacts. The real part of permeability increases by 34.18% when compared with the silicone resin coated samples at 20 kHz. In this work, a formula for calculating the total loss component by loss separation method is presented and finally the different parts of total losses are calculated. The results show that the eddy current loss coefficient is close to each other for the silicone-MnZn ferrite, silicone resin and MnZn ferrite coa...
