Recrystallization Of High Purity Aluminum, Virgil H. Griswold Jr. May 1953

Recrystallization Of High Purity Aluminum, Virgil H. Griswold Jr.

Bachelors Theses and Reports, 1928 - 1970

If a metal is first cold-worked and then heated to a sufficient temperature for an adequate length of time, the hardening properties due to cold-working disappear, and the metal will return more or less to its original state. Upon examination of the microstructure, we find that new grains have replaced the old grains through what is called recrystallization. The final size of the recrystallized grains depends upon three important variables--the degree of cold-work or deforma­tion, annealing temperature, and annealing time.
