Figure 3From: Effects of Electric and Magnetic Treatments on Microstructures of Solid Metals: A ReviewQualitative numerical simulation result of the current density distribution when an electric current passing through (a) a α-Fe sphere of radius R and (b) that with a γ-Fe nucleus of radius r (r << R) at the center by Ansys, where the conductivity σα < σγ (the dashed arrows denote the current direction) [30]Back to article page
