Cold Working
What does cold working a metal achieve?
Expand Hint
Cold working refers to physically manipulating a metal workpiece below its respective recrystallization temperature, which is a specific temperature a metal will develop new grains.
Hint 2
Unlike hot working (think welding, forging, hot rolling, etc), most cold working processes occur at or near room temperature.
Cold working is a technique used to increase the strength and lower the ductility (deform without fracture) of a metal through plastically deformation.
Cold working refers to physically manipulating a metal workpiece below its respective recrystallization temperature, which is a specific temperature a metal will develop new grains. Unlike hot working (think welding, forging, hot rolling, etc), most cold working processes occur at or near room temperature, which typically results in easier implementation, better surface finishes, superior dimensional control, better reproducibility, and lowered contamination.
Cold working increases strength, and lowers ductility.
