The behavior of dynamic recrystallization of pure nickel is investigated by uniaxial compression tests at temperatures and strain rates ranging from 873 K to 1573 K and from 2.5×10−5 s−1 to 1.0×10−3 s−1, respectively. The textures formed during dynamic recrystallization are investigated by calculating orientation distribution function. Orientation measurements of individual grains also carried out by EBSP technique. It was found that the texture varies depending on the value of Zener-Hollomon parameter (hereafter abbreviated as Z). At high Z conditions, area of high pole density is distributed from (011) to 10 degrees away from (011) to (001). No sharp textures were observed at low Z conditions. It was concluded that new grains were formed by strain-induced grain boundary migration at low Z conditions. During the migration, many twins are formed, resulting in no texture formation. The fraction of twin boundary varied depending on the value of Z, suggesting that dynamic recrystallization is available for grain boundary character distribution control.
