Abstract

BRUNA, Roberto Gerardo. Effects of hot and warm rolling on microstructure, texture and properties of low carbon steel. Rem: Rev. Esc. Minas [online]. 2011, vol.64, n.1, pp. 57-62. ISSN 0370-4467.  http://dx.doi.org/10.1590/S0370-44672011000100007.

It is well-known that variations in the thermomechanical processing can have a profound effect on the microstructure and mechanical properties of Low Carbon steels. Numerous studies have been published on the effect of composition, slab reheating temperature (SRT), hot rolling finishing temperature (FRT), coiling temperature after rolling (CT), amount of deformation during hot and cold rolling, and annealing temperature on the mechanical properties of LC steels. There are, however, some disagreements in the results presented in the literature. In this work the FRT and CT effects on the microstructure, recrystallization behavior and texture of LC steels rolled under hot and warm-rolling industrial conditions were investigated. The results in terms of the microstructure, crystallographic texture and properties are shown and discussed. In addition, this study will present the possible mechanisms responsible for the microstructure and mechanical properties observed.

Keywords : Recrystallization; textures; ferritic or warm rolling; low carbon steels; stacking fault energy.
