During the recovery stage, a furnace or other type of heating …
WebMechanisms of Recovery: The mechanism operating at low temperature is vacancy motion. This involves (i) migration of point defects to grain boundaries and dislocations, and (ii) combination of point defects. At intermediate temperature the mechanism is dislocation movement without climb. WebAnnealing works in three stages – the recovery stage, recrystallization stage and the grain growth stage. These work as follows: 1. Recovery Stage This stage is where the furnace or other heating device is used to …
