Magnetic local investigations of non-oriented electrical steels after tensile deformation

Abstract The experimental results of investigations of non-oriented steels after tensile deformation are reported. The steel samples were tested using the magnetovision method and the single strip tester. The applied deformation was up to 15% but the most significant changes were detected in the first step—at 0.5%. In several cases it was observed that after stress the homogeneity of the structure of the samples was destructed.
