Abstract : The occurrence of twinning in aluminum and the part played by twinning in the plastic deformation of aluminum has not been adequately interpreted. The structure of aluminum has been determined only by the DeBye-Scherrer powder method which does not reveal the presence of twinning. With the use of oscillating crystal techniques, the twinning is revealed in aluminum. With the demonstration of twinning in aluminum, the need for further analysis of twinning as a mode of deformation becomes more and more apparent. (Author)
