RECOVERY
This describes the processes that lead to a recovery of mechanical
properties, since deformation of polycrystalline aggregates at low
temperature typically leads to the material gaining in strength (because
the dislocations get tangled and can no longer move freely). Recovery
processes are enhanced at higher temperatures, and occur both during
deformation and subsequent to it, but are typically swamped by deformation
processes during deformation. There are a number of competing processes
that can lead to the observation of a recovered mechanical state, these
being annihilation, slips and polygonization.
