“…After heat treatment (1100 ∘ C/5 h, furnace cooling), AC magnetic properties of the ribbons are shown in Figure 7 in comparison with ultrathin sheet produced by cold rolling [6] and CVD [18] methods. It is found that, with the frequencies below 10 kHz, the core losses in this work are a little higher or as good as those produced by cold rolling and CVD process.…”

Melt spinning method has been widely applied for fabrication of Fe-based amorphous/nanocrystalline ribbons in industry. Compared with Fe-based amorphous/nanocrystalline alloys, Fe-6.5wt%Si high silicon steel is of low cost and has comparable excellent soft magnetic properties. Due to higher melting point and absence of supercooled liquid region, fabrication of Fe-6.5wt%Si ribbons is very hard and is only on lab scale. In this paper, we report that large scale fabrication of Fe-6.5wt%Si ribbons was successful and microstructures, ordered structures, and mechanical and soft magnetic properties of the ribbons were investigated. Due to rapid solidification rate, the ribbons were of ultrafine grains, and low degree of order and exhibited some extent of bending and tensile ductility. After heat treatment, excellent soft magnetic properties were obtained. Due to near-zero magnetostriction, the ribbons are promising to be used in electric devices with high frequencies where low noises are required.

Power losses of 6.5% silicon steel sheets under PWM (Pulse Width Modulation) voltage excitation were examined. The PWM wave was composed of a 50Hz fundamental wave, a 16kHz carrier frequency wave and some other higher harmonics. It was found that the power losses of the inductor cores were much larger than those of the transformer cores when the cores were driven by a PWM inverter, although such a great difference was not observed under sinusoidal voltage excitation. Power losses of the inductor made of 6.5% silicon steel sheets and conventional grain oriented 3% silicon steel sheets under PWM voltage excitation were also investigated It was found that the power losses of the inductor made of 6.5% silicon steel sheets were reduced by more than 30% compared to those of the inductor made of grain oriented 3% silicon steel sheets. This was because the grain oriented 3% silicon steel sheets had higher losses at higher harmonics found in the PWM excitation. Therefore, it was clearly shown that 6.5% silicon steel sheet was a suitable material for the inductor under PWM voltage excitation.

“…With the miniaturization and high frequency of electrical, to meet requirements of the high-frequency inverter transformers silicon steel sheet iron core iron loss of small, high permeability and small magnetostriction, increasing the silicon content of 6.5% and thinning the thickness of the steel is considered the best method. Fe-Si alloy which has 4.5%~6.5%Si having excellent soft magnetic characteristics is suggested by Characteristic of the 6.5%silicon steel evaluated by TANAKA Y etc [1][2][3][4][5] . But as the silicon content increases, the hardness of the alloy increases, ductility descends and the plastic and machining performance of 6.5wt%silicon steel have already become poor.…”

As a floppy alloy, the silicon steel with a content of Si of 6.5% has been paid much attention due to its maximum magnetic induction and minimum iron loss. However, the manufacture has been limited largely by conventional technics. By comparison, the silicon steel with a lower silicon content of 0.1%-4.0%, which was manufactured by conventional technics, also has a limited application. In this work, Molten Salts Electrodeposition has been employed to produce Fe-Si alloy. Technological parameters including influence of Molten Salts Electrodeposition technic in aggradation layer appearance and distribution of silicon content along with thickness. The results also show that the size of superficial particles on deposit layer increased gradually, the thickness of deposit layer was proportional to the current density on the deposit layer of Fe-Si.
