Recrystallization texture evolution in HSLA steel

Abstract

The role of ferrite and pearlite constituent phases on the recrystallization texture of an HSLA steel is addressed. For the purpose of monitoring the microstructure and texture evolution, two different starting hot bands obtained after hot rolling above and below the Tnr are considered. 80% cold-deformed and subsequently recrystallized samples from each of these hot bands are examined with high-resolution electro-scanning microscopy. Recrystallization kinetics are evaluated with a Vickers microhardness tester. Results support a faster recrystallization kinetics in below Tnr (BT) sample. Preliminary results suggest the reappearance of hot band texture components at the onset of recrystallization.
