A heavy-reduction controlled rolling process with approximately 75% thickness reduction was carried out to investigate the microstructural evolution including texture development, focusing on the formation of a bimodal structure of 0.2% carbon steel with heating temperatures of 700, 800, 900, and 1000 o C. Upon increasing the heating temperature from 700 to 900 o C, the microstructure was refined and precipitates such as Fe 3 C were uniformly distributed throughout the microstructure. For the microstructures control-rolled at heating temperatures of 900 and 1000 o C with average ferrite grain sizes of 1.34 and 1.63 µm, respectively, a bimodal structure
