Lab Incharge: Neeraj Kumar
Course Objectives:
- Provide the student hands-on experiences in materials science through laboratory experiments that explore the properties and structure of materials and the interplay between processing and performance.
- To develop students’ experience a wide range of materials phenomena
- To develop the students’ knowledge of techniques of micro structural analysis of ferrous metals.
- Development of basic analysis skills across a broad core of materials science applications
In this lab Experiments on Material Science and Experiments on Material Testing are to be conducted as given below:
List of Experiments:
Experiments on Material Science (at least 5 of the following):
- Preparation of a plastic mould for small metallic specimen.
- Preparation of specimen for micro structural examination-cutting, grinding, polishing, etching.
- Determination of grain size for a given specimen.
- Comparative study of microstructures of different specimens of different materials (mild steel, gray C.I., brass, copper etc.)
- Experiments on heat treatment such as annealing, normalizing, quenching, case hardening and comparison of hardness before and after heat treatment.
- Material identification of, say, 50 common items kept in a box.
- Experiment on Faraday’s law of electrolysis.
- Study of corrosion and its effects.
- Study of microstructure of welded component and HAZ. Macro & micro examination of the welded specimen.
- Study of Magnetic/ Electrical/Electronic materials.
Experiments on Material Testing (at least 5 of the following):
