During which phase of annealing does a wrought metal experience a sharp drop in tensile strength accompanied by a rise in ductility?

Explanation

The recrystallization phase is characterized by the formation of new, strain-free grains, which leads to a significant reduction in tensile strength and an increase in ductility. The recovery phase primarily reduces internal stresses without major changes in strength or ductility, while the grain growth phase involves enlargement of grains but does not cause such a rapid change.
