Abstract Scope |
The microstructural evolution during recrystallization is an important phenomenon in metals and has a large effect on the mechanical strength of the metals. Numerous phase-field models predicting this phenomenon have been developed; however, they do not include nucleation theory for recrystallization which makes it difficult to practically use. In this study, static recrystallization behavior of 1100 aluminum was observed in-situ, with a focus on the nucleation. Cold rolled 1100 aluminum with 80% reduction was heated in FE-SEM equipped with EBSD. Main components of crystal orientations after the heating were {114}<-1-72>, {013}<0-31>, {013}<100>, and Cube{001}<100>. Area fractions of preferred orientations varied above 200 degrees Celsius. Small recrystallization grains were observed at around 200 degrees Celsius, some of which grew during holding at 280 degrees Celsius without changing the crystal orientations. |
