Cold work, recovery, recrystallization

Cold work, recovery, recrystallization. Example:Single crystal. State I:Annealed metal. Fairly strong and ductile. r ? = 10 6 /cm 2. Low internal energy: stable. Cold worked. State II:Cold worked metal. r ? = 10 10-12 /cm 2. Very strong and brittle. High internal energy: not very stable.
