As- received 2090 Al- Li hot- rolled plate was homogenized at 482 °C for 10 h and cold worked to 95% reduction in thickness. The rolling modes were varied. One group of samples was rolled longitudinally parallel to the hot- rolling direction, the second transversely to the rolling direction, the third at 45° to the rolling direction, and the fourth in all three modes. All four groups were subsequently annealed at 456 °C for 24 h. The effect of varying the rolling mode on the ductility and strength was studied by examining the kinetics of softening as a function of the annealing time. All the groups recrystallized in less than 1 h with a coarse, elongated grain structure. Although the strengths of the different groups were similar, the ductilities varied significantly.
