| Abstract Scope |
Increasing the silicon content of electrical steel is known to assist in achieving near-zero magnetostriction and low high-frequency core losses. Thus, this study investigates the impact of silicon addition after hot rolling on the microstructural characteristics of grain-oriented electrical steels. The aim is to optimize the hot rolling schedule for maximizing the preferred Goss ({1 1 0}<0 0 1>) grains. The experimental approach employed physical simulations of the hot rolling process (i.e., based on industrial rolling schedules) through a laboratory-scale hot torsion test method, emulating plane strain deformation condition. Two types of electrical steels with different silicon concentrations (1.3 wt% and 3.2 wt%) were subjected to varying reduction rates and interpass times to determine the optimal rolling schedule. The study found that the extent of dynamic recrystallization and recovery during hot rolling, which are influenced by the reduction rate and interpass times, has a significant impact on texture evolution. |
