| Abstract Scope |
Changing the processing history and increasing the silicon content of electrical steels are known to assist in achieving near-zero magnetostriction and low high-frequency core losses. Thus, this study investigates the impact of hot torsion deformation and silicon addition on the microstructural characteristics of electrical steels with silicon contents of 1.3 and 3.2 wt.%. Specifically, torsion tests were performed at 1000°C with an applied strain and strain rate of 1 and 1 s⁻¹, respectively, followed by annealing heat treatment at 750ºC for up to 220 minutes. Results showed that R//<100> (i.e., R is the radial direction from the center of the cylindrical samples) were generated by shear stresses. The proportion of R//<100> increases from the center to the surface, consistent with the linear change in strain from the center to the surface of the torsion sample. This approach can potentially reduce the core losses of electrical steel laminates for rotor/stator applications. |
