摘要：
In the present work, microstructure optimization strategy driven by differential speed rolling (DSR) deformation followed by annealing was used to enhance strength and ductility of low-carbon steel (LCS). In this regard, LCS samples were deformed by DSR at a roll-speed ratio and total thickness reduction of 4:1 and 75%, respectively, and the DSR-deformed samples were then annealed at various conditions. The results showed that the sample deformed by DSR and annealed at 773 K for 6 h exhibited a combination of improved strength and good ductility. (C) 2019 Elsevier B.V. All rights reserved.
