Effect of the Si and Al Content in Ferritic Electrical Steels on the Flow Behaviour and Dynamic Softening in Hot Rolling

摘要

FeSi steels with and without addition of Al are widely used as electrical steels. To improve the knowledge of the effects by the addition of Si and Al on the hardening and softening under hot rolling conditions, the behaviour of the flow curves in a wide range of temperatures and deformation velocities have been studied.
