Material Science and Metallurgy

Hello,

I would like to show very first how to visualize the subject. For this, we should have total concentration. To avoid obstacle coming in front of us, we will follow the following steps.

Close your eyes, try to identify any Object.,Whatever it may be and ask the following questions yourself.

1. What is that object made from?
2. What are the properties that an object supposed to have to perform functional need?
3. Is that object has this property by birth, or it introduced by some mean? If yes, what are that processes?
4. How one can come to know the properties of any object? Available instruments for that.
5. What might be failure problems faced by that object, and what preventive measures we can do?

This is a reverse engineering way of learning and teaching,

Eg.

1. I imagine object_ Helmet.
2. It should be tough enough if impact occurs on it and at the same time smooth inside to protect the head from injury.
3. All those things not by birth and artificially added by material selection to selecting mfg, the process followed with Heat Treatment.
4. Confirmation properties by Impact Test, Hardness Test, etc.
5. It may corrode, get scratched, and wear tear, so the appropriate coating is necessary for the same.

These all things you will get from nothing from Material Science and Metallurgy subject. All that complicated things we have to step by in this subject.

I hope you will better understand the importance of this subject.
