| Abstract | The present work examines the effect of strain and Zener Hollomon parameter, Z, on deformation and recrystallization of Ti-IF steel deformed in the warm temperature region. Torsion tests were performed at temperatures of 765oC and 850oC and strain rates of 0.003s-1 and 1s-1. For some conditions, an annealing treatment at the temperature of deformation was carried out using a fluidized bed furnace. Electron Back Scatter Diffraction (EBSD) maps were implemented to study the microstructure evolution. At a low value of Z abnormally large grains formed during annealing. At the higher values of Z, a more classical recrystallization reaction occurred during annealing. The latter is more desirable in most commercial applications. |
