what is the effect of full annealing compared to normalizing
Annealing (metallurgy)
The three stages of the annealing process that proceed as the temperature of the material is increased are : recovery , recrystallization , and grain growth . The first stage is recovery , and it results in softening of the metal through removal of primarily linear defects called dislocations and the internal stresses they cause . Recovery occurs at the lower temperature stage of all annealing processes and before the appearance of new strain - free grains . The grain size and shape do not change . The second stage is recrystallization , where new strain - free grains nucleate and grow to replace those deformed by internal stresses . If annealing is allowed to continue once recrystallization has completed , then grain growth ( the third stage ) occurs . In grain growth , the microstructure starts to coarsen and may cause the metal to lose a substantial part of its original strength . This can however be regained with hardening .
