Evaluating the flow stress of electrical steel under cold rolling in terms of the strain-rate hardening effect

Abstract

The flow stress of the Fe+3%Si electrical steel under actual cold rolling conditions is evaluated on the basis of the approximation of the existing data on the work hardening and strain-rate hardening of this steel during cold tensile testing. It has been discovered that ductility is significant during electrical steel cold rolling and, besides, that its value is lower for large strains and strain rates than for low strains and strain rates. © 2016 Author(s).
