The temperature at which the new grains are formed in the metal is called

A. Lower critical temperature

B. Upper critical temperature

C. Eutectic temperature

D. Recrystallisation temperature

Answer: Option D

Solution(By Examveda Team)

Recrystallization is the process in which deformed grains of the crystal structure are replaced by a new set of stress-free grains that nucleate and grow until all the original grains have been consumed. The process is accomplished by heating the material to temperatures above that of crystallization.
