摘要：

Recrystallization and grain growth of a cold-rolled gold sheet with 9.8 pct reduction in area (RA) were investigated with electron backscatter diffraction (EBSD) and X-ray diffraction (XRD). Gold with some dopants (Be, Ca, and La) was used in this research and its' recrystallization temperature was 320 degrees C. Isothermal annealing experiments at 400 degrees C, 500 degrees C, and 600 degrees C were carried out for the cold-rolled gold sheet, and recrystallization texture was examined. In the cold-rolled. gold sheet, alpha- and beta-fibers were measured mainly and some shear texture components were found on the surface. Shear texture components remained on the, surface for 2 hours at 400 degrees C and were consumed by other recrystallized grains after 24 hours at 400 degrees C. Microstructure and texture evolution during in-situ annealing at 400 degrees C were investigated from the cold-rolled state to the fully recrystallized state using EBSD. Most of the newly, recrystallized grains came from the deformed beta-fiber regions and consisted of beta-fiber, cube, and other random orientations.
