Metal Deformation Processes

Which of the following is NOT a metal deformation process?

• Forging

• Rolling

• Casting

• Extrusion

What is the primary function of rolling in metalworking?

• To join two metals

• To remove material

• To reduce thickness

• To harden the metal

Which of the following processes is primarily used to shape long, continuous lengths of material with a uniform cross-section?

• Forging

• Extrusion

• Rolling

• Drawing

In which metalworking process is the metal heated above its recrystallization temperature?

• Cold working

• Hot working

• Annealing

• Quenching

What is the main difference between open-die and closed-die forging?

• Open-die is used for larger parts, closed-die for smaller parts

• Closed-die forging provides better dimensional accuracy

• Open-die forging uses less force

• Closed-die forging cannot be used for metals

Which process is used to create seamless tubes?

• Extrusion

• Drawing

• Piercing

• Rolling

In drawing, the diameter of the metal wire is reduced by:

• Compressing it between two rolls

• Pulling it through a die

• Heating and hammering it

• Melting and casting it

What is the main advantage of cold working over hot working?

• Improved grain structure

• Higher ductility

• Better surface finish and dimensional accuracy

• Lower energy consumption

Which metal deformation process involves compressing the metal between two flat or contoured dies?

• Forging

• Rolling

• Drawing

• Bending

Which of the following is a hot working process?

• Annealing

• Cold drawing

• Cold forging

• Hot extrusion
