Make a schematic plot of room temperature ductility versus t

Make a schematic plot of room temperature ductility versus the logarithm of annealing time at constant annealing temperature (T1) for a metal alloy that had been cold-worked prior to the annealing treatment. Assume that recrystallization occurs at T1. Superimpose and label on this plot, a curve for the same alloy that was subjected to the same percent cold-work, but that was annealed at a lower annealing temperature, T2.
