1. Describe the relationship and differences between substitutional and interstitial solid solution?
2. What do you mean by cooling curve? Describe how does time temperature cooling curve of the alloy of eutectic composition different from that of a pure metal?
3. Describe in detail:
1) Eutectic reaction
2) Eutectoid reaction
3) Peritectic reaction
4) Peritectoid reaction
4. Sketch Iron -Carbide equilibrium diagram and mark on it all important temperature and composition fields.
5. Elements A and B melt at 7000°C and 10000°C respectively. Sketch a typical isomorphous phase diagram between the elements A and B.
6. Elements A and B melt at 7000° C and 10000° C respectively. They form a eutectic at 35%A at temperature 5000°C. Sketch a typical phase diagram between A and B.
