Prof. R. N. Ghosh thank you very much. These Lectures of IITs proved out to be greatly useful for me. Just some days ago results are out and I'm passed in all subjects. Great credits to NPTEL...

For the Past 4 years. I have been afraid of this particular topic from Material Science. Thankyou sir for making it so easy to understand.

Honour to learn from such an experienced metallurgist, thank you sir

Truly amazing explanation. Everything is crystal clear. Great job Sir.

sir before I watched this video I knew nothing about iron corbon diagram but am sure now I know very well really awesome.....

There are so many lectures available in this perticular topic but this one is best among them..thank you sir..🙏..

Very good master !!!!! Clear and solid explanation ...!!!!!! Cheers from Ecuador.

Sir, Awesome way to explain

One of the best....lacture and simple to understand

No where else was ledeburite explained as well as here. Thank you!

sir, u are very great........ i recommend u alot for students who are slow learners like me.... very good video

Great video and right explanation.

Awesome explanation!!! thanks :)

excellent!! very helpfull for me!! thanx 4 uploading...

Very suberb explaination all my basic doubts have got cleared now, It will really be nice if also a video of tertiary Fe-Fe3C is made

Many thanks professor! From Brazil. Very helpfull

Good explanation Because it is very complex and typical topic

Very good presentation , thank you so much.

This helped me understand the concept very well, I read through material science by phaneesh and I can say I am very confident now, this is the hardest part of msm and now it seems easy. thank you very much,sir. Helped me a lot.

Why we don't have Face center tetragonal bravias lattice, even in case of orthorhombic where all three sides different i.e, a,b,c all are not equal to each other, but still we have simple cubic, body centered, face centered and end centered. why so in case of tetragonal, only simple cubic and body centered, not face centered?

I see two lecture videos... which one is latest

Thank you so much Sir ji

@yuanshanhuo3285

I think what he said is to calculate the cementite in Pearlite. Because as its cooling down below the eutectoid isotherm, only the autenite is going to produce ferrite plus cementite or in all, pearlite. Therefore to calculate the percentage of cm in Pearlite, it should be ab/ad which is around 6%. But to know the cm% in total, which is ferrite plus pearlite, use 6% times the percentage of the pearlite, which is nearly 50%. Thus in total, the cementite is around 3%.

@Henrik.Yngvesson

6 жыл бұрын

On the left side of "C" there is no cementite forming at all just ferrite and perlite where perlite increases with increased carbon content and at 0,8% you have 100% perlite. On the right side of "C" it's starting to form cementite and you can calculate the percentage of cementite and perlite just like you calculate ferrite and perlite on the left side of "C".

Authors define the eutectoid point of the FeC diagram with different% C (example: 0.77%, 0.86% and 0.83%). What is correct value?

@Lillebroor

I´ve always used 0.76wt-%C as eutectoid point. (And 0.022wt-%C and 6.70wt-%C)

eutectoid point varies with alloying elements.So it will depend on the alloys present in the steel.In general it is .77%C.

U should tell student how much of cementite but not just throw the question to let student find out, the reason student come here to watch ur video reason is they need some one to show them

After watching this video, I guarantee no teacher in India can teach iron carbon equilibrium diagram. I know they can explain it by reading it. But no, they can't teach. What is shown in the video is mere fact stating.

Not worthy, still our Indian Lectures are doing lesson traditionally, it is so boring!!! How carbon is to be soluble in solvent like iron,,,,on what basis you are giving assurance whether carbon is going to soluble or not,,,, you should show practical things,,, that is the draw back of Indian country
