Effect of Electropulsing on Recrystallization and Mechanical Properties of Silicon Steel Strips

Keywords： Recrystallization

Electropulsing-induced recrystallization and its effect on mechanical properties of oriented silicon steel strips （Fe-3.0%Si） were studied by optical microscopy, scanning electron microscopy and electron back-scatter diffraction. The results indicated that electropulsing accelerated recrystallization, and decreased the temperature of recrystallization. Electropulsing favors refinement of the grain structure of the alloy. Effects of electropulsing on strength and elongation of the alloy were discussed from the point view of dislocation dynamics, microstructural changes, and electropulsing kinetics.
