Abstract: The microstructure, texture and mechanical properties of an ELC steel and an IF steel both produced by hot rolling in ferrite region, cold rolling and annealing were compared. The results showed that deformation bands are dominant in the ELC while equiaxed grains grow in the IF after hot rolling in ferrite region. The hot band texture of ELC includes not only strong α-fiber but weak γ-fiber, while that of IF is mainly the γ-fiber. However, after cold rolling and annealing, ELC presents mainly the γ-fiber texture with peak at {111} <112> , and IF presents the strong and well-proportioned γ-fiber texture which provides obviously higher strength than ELC. Moreover, the values of mean plastic strain ratio and percentage elongation of IF are 0.6 and 5% higher than ELC, respectively, with higher tensile strength and lower yield strength provided.
