Cold working processes: Below the recrystallization temperature if the mechanical work is done on the metals , there will no grain growth but it must be grain this integration elongation , the process is known is cold working processes. In cold working process greator pressure is required than that required in hot working. As the metal is in a more rigid state. It is not permanently deform until stress exceeds the elastic limit. Most of the cold processes are performed at room temperature , the different cold working processes are 1: Drawing · Wire drawing · Tube drawing · Blanking · Spinning 2: Sequeezing · Coining · Sizing · Riveting 3: Bending · Angle bending · Plate bending · Roll forming 4: Shearing >Punching >Blanking > Trimming > Perforating >Notching >Launcing >Slittig 5:Extruding for more details please click here http://www.flixya.com/post/leopardans/2232205/cold_working_processes"
