| Abstract Scope |
In this study, the effect of titanium on the microstructure and magnetic properties of high-silicon electrical steel is discussed. The addition of titanium successfully reduced the grain size through constitutional supercooling, thereby decreasing the eddy current loss. However, it also led to the formation of Fe₂Ti precipitates, which hindered domain wall motion and consequently increased hysteresis loss and anomalous loss. For low-frequency applications, where hysteresis and anomalous losses are dominant, titanium addition resulted in a higher total core loss. In contrast, at higher frequencies of the external magnetic field, the eddy current loss becomes the dominant component of the total core loss. As a result, the minimum total core loss was observed in the sample containing 3 wt.% titanium at an external magnetic field frequency of 1000 Hz. |
