20ME11T- MATERIALS FOR ENGINEERING

Course Outcomes (COs)

1. Illustrate the various properties of materials in engineering.

2. Select relevant ferrous materials, cast iron, nonferrous metals, and advanced materials for engineering applications.

3. Adopt the international practice of materials designation and coding systems.

4. Identify relevant heat treatment processes for altering the properties of metals.

5. Recommend relevant surface treatment processes for protecting the surface of materials.

Learning Resources

1. Select any five objects (3 metallic and 2 nonmetallic) which will be used in the laboratory and list the material of selected objects.

2. Prepare the material list of given tools and commonly used items such as razor blade, knife, scissor, hacksaw blade, carpentry chisel, fix spanner, etc. Also, give reason(s) for using such material and discuss your answers with the teacher.

3. Take dilute acid which is commonly used at home for cleaning purposes and put one scrap iron piece and one nonferrous metal piece in it for a minimum of 12 hours. Take out these two pieces by following all safety norms/steps (without touching the acid) and observe the changes. Discuss with your teacher.

4. A group of 3-5 students will visit a LOCAL AUTOMOBILE REPAIR SHOP and will identify at least 5 nonmetallic components for a given AUTOMOBILE/assembly. Also, list the material of identified machine/assembly components.

5. List at least three questions individually which you would like to ask for the following:
   i. Comparison of iron and fiber-reinforced plastic.
   ii. Comparison of strength between wood and cast iron.
   iii. Annealing-heat treatment process.
   iv. Materials used for the construction of any bike.
   v. Materials used for the construction of any home appliance, like a mixer, washing machine, iron, etc.
   vi. Any other relevant activity added by the teacher, including preparing an industrial visit report.
