【 摘 要 】

With focus on annealing twins, the microstructural evolution of cold rolled high purity aluminium was characterized in-situ during annealing using the electron backscatter diffraction technique. It was found that annealing twins developed during recrystallization. Many but not all of the twins were gradually removed during grain growth. The grain boundary energies of all the boundaries in a network associated with the twins are estimated and reasons why most twins disappear while a few remain are discussed.
