Which outcome arises from exceeding the annealing temperature during wrought iron production?

💡 Explanation

Exceeding the annealing temperature results in grain growth because thermal energy increases atomic mobility, therefore larger grains form, reducing wrought iron's overall strength, rather than refining the grain structure which is needed for stronger tensile strength. Work hardening actually reduces the grain size..
