Q. What is the procedure of hot working?
A process is defined as hot working if it takes place when the workpiece is above the recrystallization temperature.
Hot Working Advantages
• Hardness and ductility of metal is not changed.
• Porosity is eliminated.
• Structure is improved by reforming smaller crystals.
• Large shape changes are possible without ruptures.
• Smaller, faster acting machines.
• Impurities are broken up and distributed throughout material.
• Surfaces need not be clean and scale free.
