Objective:

This course essentially aims at making the students gain hands on experience on the equipment used for metallographic specimen preparation, optical microscopy and image analysis. The course would also have some study practices where in the construction of basic crystal structure models, phase diagrams are included.

1. Preparation of precise crystal structure models and study of their structural parameters, calculation of packing factor.
2. Preparation of specimen for metallographic examination.
3. Study of principle, construction and salient features of different classes of metallurgical microscopes.
4. Calculation of Grain Size and ASTM Grainsize number and determination and inclusion content in the given materials.

Microstructural analysis of ferrous alloys

5. Identification and analysis of microstructure of hypoeutectoid, eutectoid, and hypereutectoid steels.
6. Identification and analysis of microstructure of Alloy steels.
7. Identification and analysis of microstructure of different classes of cast irons. 

Microstructural analysis of ferrous alloys

8. Identification and analysis of microstructure of various nonferrous alloys viz.,
   • Aluminum base
   • Copper base and
   • Titanium base alloys

Construction of phase equilibrium diagrams

9. Construction of graphical representation of ismorphous phase equilibrium diagram and study of phases, invariant points, and invariant reactions.
10. Construction of graphical representation of eutectic phase equilibrium diagrams and study of phases, invariant points, and invariant reactions.
11. Construction of graphical representation of Iron-Iron Carbide phase equilibrium diagram and study of phases, invariant points, and invariant reactions.

Outcome:

The student will be able to identify and analyze the microstructural features of the given ferrous/nonferrous metallic sample. He would also have thorough theoretical approach in construction of phase diagrams.
