EFFECT OF TEMPER ROLLING ON THE STRAIN HARDENING OF A NON-ORIENTED ELECTROTECHNICAL STEEL
Abstract
The present work deals about difference in strain-hardening at rolling with various rolling temperature (RT, 100°C, 250°C) of three samples (FC1, FC2, FC3) from non-oriented electrotechnical steel. The study was performed by means of microhardness testing method. The sample which was rolled at room temperature has the most strain hardening below the surface, which relates with the current technological conditions in the rolling. When we rolled the samples at increased rolling temperature (100°C, 250°C), the most strain hardening is in the center of the sample which relates with the gradient of defromation trough the cross- section of material.
