Abstract
Isothermal annealing of a 0.30 mm thick sheet of cold rolled 3 wt% aluminum-iron was conducted at 950°C, in order to investigate the effect of silver on the secondary recrystallization behavior. By the addition of 0.018 wt% silver, the normal grain growth of the primary grains was effectively retarded and a strong Goss texture was developed by the secondary recrystallization. It is considered that such an element as silver which has a very low solid solubility in iron segregates preferentially at the grain boundary and thereby the free energy of activation for boundary migration of the matrix grains is increased.
