Question Paper
1. What do you understand by atomic packing factor Calculate the atomic packing factor for a Hexagonal Closed Packed and Base Centred Cube Crystal System.
2. Distinguish between fatigue failure and fatigue strength. Briefly explain the measures that may be taken to increase the resistance to fatigue failure of a metal alloy.
3. Draw the Fe-C phase diagram. Level all the phases and temperature properly. Also differentiate between hypoeutectoid and hypereutectoid steels.
4. Define the term Heat Treatment? Why are steels heat treated Discuss the major defects in steel due to faulty Heat Treatment.
5. Explain the working of Cupola Furnace with the help of a neat sketch.
