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.
