Recovery recrystallization and grain growth

WebbAnnealing furnace consists of three stages; recovery, recrystallization, and grain growth. The recovery phase occurs at a lower temperature of the process. This is where the material being annealed is softened by the removal of linear defects called dislocations and the internal stresses produced by them. Webbgrain boundaries which are most relevant to recovery, recrystallization and grain growth and will not attempt to give a full coverage of the subject.
