The advantages and disadvantages of hot working and cold working.

Expert Solution & Answer

Answer to Problem 1QP

The advantages and disadvantages of hot working and cold working is given below:

Explanation of Solution

Hot working:

Advantages:

1. Larger deformations are achievable and it can be repeated.
2. It requires less energy to achieve the required deformation as compared to cold working.
3. The grain structure of the material was refined. Thus, the mechanical properties of the material was improved.

Disadvantages:

1. Hot working carried out at high temperatures this causes surface oxidation which gives poor surface finish.
2. Difficult to achieve closest dimensional tolerances.
3. Loss of metal during hot working.

Cold working:

Advantages:

1. High quality of surface finished can be achieved.
2. Variety of mechanical properties can be achieved.
3. Close dimensional tolerances achieved easily.

Disadvantages:

1. Ductility of the material was reduced.
2. The cold working process is quiet complicated and expensive.
3. It require more energy to achieve the required deformation.
