Effect of post-rolling cooling on the hot-rolled microstructure and texture of a new medium-carbon steel

Abstract Thermomechanical processing consisted of hot-rolling in the austenitic region with deformation both above and below non-recrystallization temperature. Immediately after rolling, specimens were directly quenched water to three different temperatures 560 °C, 420 °C room The first two samples, which 560° C 420°C, immediately cooled slowly furnace. microstructure samples mostly comprised upper bainite whereas mainly lath-type bainite. sample direct-quenched temperature was martensite. transformation texture all at midthickness position showed same general texture, ? ? fibers components high intensities close transformed copper {112}<110> , brass {111}<112> rotated cube {001}<110> components. However, produced slightly more intense compared bainitic samples. local near rolled surface owing sever shear features consisting major {112}<111> {110}<112> {110}<111> .
