What is recrystallisation temperature and its formula?
Answers
Answer:
Explanation:
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. This process is utilized in the annealing of steel, to eliminate all the effects of strain hardening such as heavy plastic deformation produced during cold working.
Answer:
Recrystallization temperature is a particular temperature point below the melting point of a metal (or material). Usually, metals, in microscopic scale are made up of grain like particles.The recrystallisation temperature for steels is typically between 400 and 700 °C. The recrystallisation conditions, such as heating rate and soaking time depend on the degree of cold work and the steel composition. The rate of softening increases rapidly as the annealing temperature reaches A1 point.
