Abstract

The triple junction features of 0.5 wt.% Si electrical steel in electrically assisted forming were investigated. Specimens were electrically stretched, measured with electron backscatter diffraction (EBSD) method. The results show triple junction curvature, and the difference between the maximum and minimum dihedral angles and specific triple junctions are promoted. It is concluded that increased deviation from the equilibrium of dihedral angles can be attributed to the increased triple junction curvature induced by electric current. The increased triple junction curvature enhances the driving force for triple junction motion and reduces the retarding effect of particles on the motion of triple junctions.
