| Abstract: | Rolling large- diameter hardened steel balls over the surface of high- permeability grain- oriented electri-cal steel allows lines of plastic deformation to be laid down. Choice of proper Young’s modulus and ball diameter enables artificial grain boundaries to be created, producing appropriate domain refinement and loss reduction. |
