Answer
The advantages of cold working are:
1. A high quality surface finish.
2. The mechanical properties may be varied.
3. Close dimensional tolerances.
The disadvantages of cold working are:
1. High deformation energy requirements.
2. Large deformations must be accomplished in steps, which may be expensive.
3. A loss of ductility.
The advantages of hot working are:
1. Large deformations are possible, which may be repeated.
2. Deformation energy requirements are relatively low.
The disadvantages of hot working are:
1. A poor surface finish.
2. A variety of mechanical properties is not possible.
