What are the advantages and disadvantage of cold working of a metal?

Cold working is the plastic deformation shaping process of metals which is performed below recrystallization temperature. Usually, recrystallization temperature is 40% of melting point temperature (TR=0.40xTM). Advantages are; no oxides on the surface after operation, no hydrogen embrittlement, lower costs for process and equipment, hardening from strain. Disadvantages are; stress in the body therefore mostly it needs recovery process, much more load power necessity for plastic deformation, it becomes brittle depends to cold working percentage.
