Mod-01 Lec-23 Iron-Carbon Phase Diagram

[@omkarshinde2798]

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...

[@EngineerToday]

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.

[@md.fazlerabbi1247]

sir nickel carbide diagram and iron carbide diagram both are same? please let me know

[@DeepakKumar-ro4vt]

@@md.fazlerabbi1247 its same composition is different rest are temperature difference.

[@100Akashpaul]

Me too

[@Mech.Masters]

I HAVE GONE THROUGH ALL VIDEOS ON IRON CARBIDE DIAGRAM, BUT THIS IS THE ONLY VIDEO WHERE I FOUND THAT THE PROFESSOR IS CONFIDENT ABOUT WHAT HE IS TEACHING.

[@md.fazlerabbi1247]

sic nickel carbide diagram and iron carbide diagram both are same?

[@baibhavvikas1767]

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

[@deamonofshiva]

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

[@bhagyaaggarwal7964]

Watch at 1.5x . Thank me later .

[@khanskitchenchronicles]

Bhagya Aggarwal bhai bahut sahi bole yaar This one is too much slow Mujhe neend aa rahi thi isko sunkar Now after playing on 1.5x speed, lecture seems good

[@rahul8145]

Works even at 2.0x

[@suyashchopra4402]

I tried on 1x, 1.25x, 1.5x and 2x. At 1.25x it is best for any teacher.

[@seamaxmarineservices2645]

Thanks!

[@pradeeptripathi6415]

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

[@gasperbizjan3171]

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

[@sodapop1205]

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.

[@lavme]

+prajwal nagabushan hello brother can you send an Ebook of Material science by phaneesh ?. a link here or e book on my mail id [e-mail] Thanks in advance.

[@sodapop1205]

+Lav Mehta hey! I have a hard copy. I don't have a soft copy. it costs no more than 100 rs on used ones. trust me, it's a worthy investment.

[@lavme]

+prajwal nagabushan :-) it's ok brother but i am not in india so i cant have a hard copy here .so i was searching for a e book... But anyways brother more or less main concepts are clear from video here... THanks a lot for the Reply man.

[@sodapop1205]

+Lav Mehta it's okay! yes! this video is very good!

[@sheremetbyevo]

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

[@vigneshraveendran7563]

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

[@areyouexculibar1961]

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

[@wernerhartl2069]

Great explanation of Fe-C diagram.

[@omkarshinde2798]

At 18:46 timing, a mistake is there. In Delta ferrite, solubility is high. But sir said, it's lesser than alpha ferrite . No doubt video is great.

[@k_venkata_ramana]

He said high

[@rajkaushal2737]

but he has written correct

[@rahulpanchal8364]

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

[@clebermarcio1]

Many thanks professor! From Brazil. Very helpfull

[@VijayVijay-hw8zn]

At 38:00 min cementite 14%means 1/7 .....so individual ratio cementite:ferrite 1:6 ...but sir told 1:7

[@dailysports4704]

Good explanation Because it is very complex and typical topic

[@mohammedusamabaig4790]

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

[@parmalchouriya738]

Great video and right explanation.

[@montagnanicarlo]

Superb lesson, many thanks from Italy!

[@RAD7816]

Are you by any chance working in an industry related to induction hardening?

[@aliahsan844]

please some explain hydrogen-induced variations in mechanical properties of grey cast iron

[@shaileshharchekar4877]

Voice is very much low. Content is best.

[@masoodanwar9950]

Sir, Awesome way to explain

[@HimanshuSharma-xn6uc]

Why this is part of chemistry why??

[@NeerajTiwari2828]

Excellent Explanation Sir

[@marceloschiavo7624]

Very good presentation , thank you so much.

[@pauloe.3046]

very good Dr!!

[@surajmishra3976]

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?

[@sheetalpatel9663]

thanks Sir and ase hi or ache video bnate rhe

[@elsayyidmostafa1896]

thanks a lot this is the only video I had understood

[@luizmartinssouza7867]

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)

[@anantmishra4608]

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

[@J4m5w8t7]

can any one send the link of playlist containing previous classes

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

[@sumanmukherjee7481]

Thank you very much sir for this awesome lession

[@jagadishshetti6937]

awesome....!!!!!

[@rahulguha4889]

Please sir.. give a lecture on ferro alloy.

[@ManishaKumari-xn4km]

why iron iron carbide phase diagram starts with 400C?

[@suyashchopra4402]

400 C !!!!! Are you sure ?

[@haydenborrie9831]

Awesome explanation!!! thanks :)

[@ramuduadavi6983]

[@SapePrasanna]

Sir super.chala detailga chepparu

[@md.fazlerabbi1247]

nickel carbide diagram and iron carbide diagram both are same? please let me know

[@JaiswalNimesh]

Really Very Good :)

[@md.fazlerabbi1247]

any one know nickel carbide diagram and iron carbide diagram both are same? please let me know

[@KumarNishantRanjanSinha]

Excellent !

[@Supermanspider12345]

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

[@lisho6806]

Thank you Sir

[@hardiklad9512]

In BCC how each face is shared by 2 unit cell at 9:15

[@hardiklad9512]

Please rely if anyone knows

[@RahulKumar-tz7ik]

If we will take 2 similar cube and keep them side to side 1 face centred atom will be share by 2 faces

[@bachaspatidas7282]

very useful.

[@arjavvashi5317]

how can someone dislike this lecture?

[@supunmalinthasandanayaka885]

Good Vedio

Great sir thnkyou

[@karthivp6481]

you are simply awsome .. thank you soo much

[@santanuchatterjee4370]

Good

[@skysumanth2479]

highly complexity

[@VascoMonteirosChannel]

What Is the amount of % Cementite he talks about at 42:35 ? Thank yoU!

[@SirDavothe2]

Man I wish someone had answered this. I hate when lectures do this, there is nothing gain from it.

[@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]

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".

[@akashkumar-hu2dh]

Cementite/ferrite =ab/bc Cementite = 50%

[@avaes5260]

thank you so much for this

[@VikramKumar-qo3rg]

Thank u sir...

[@yogabrindha5640]

Best

[@AbcDef-ju3ky]

I wish here in Turkey my material science teacher know English as much as you know, all he do is just reading the slides...

[@vikash126]

i wihh in turkey u know englihh. Thank very much. (s,s)

[@sharonsamuel73]

Thank sirjii

[@vimlenduvatsayan1367]

Thanks sir

[@ghanashyamdileep5432]

if you have an exam the next day and you want a quick explanation, look elsewhere. Way too slow

[@farooq8fox]

Vishal its slow even on play back, nptel is not meant for 1 day knowledge anyway.

[@zohaibzafar5135]

Play 2x...

[@peetamanideepsai8096]

Ghanashyam Dileep .in the same situation

THHNX A LOT SIR

[@ParvezAlam1994]

ye subtitle dena jruri tha... pura lectre khraab kia esne....

[@nitinkabadi]

Parvez Alam you could'ave shoved off the subtitles u muppet.

[@shardul010989]

This was just perfect dose

brother god spoke to me and said the answer is aluminum. I do not know what this means I pray for you. I mean no harm I apologize he has taken me to you

[@oceanomariel6601]

thank U very much

[@atharshaikh27]

For beginners watch 1.25x No need of thanks

[@itsxerxes6754]

ah yes quite elementary 5Head

[@akshitchoudhary877]

Itna dhire padhata hain ye 2x pe dekhna pada Plz sir teach fast and speak fast

[@snakergomzi7997]

please sir make in hindi

[@YantrikPathshala]

gomzi kumar u can go to my channel for this video in Hindi & learn it in easily way

[@YantrikPathshala]

agar aapko achha laga to subscribe aur like kare hum aage v achhe achhe video late rahenge

[@_aswin__]

Very bad

[@thomousdesouza5675]

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

[@mhc6148]

those topics will cover in metallurgy lab not in class bro

[@sahilrajeshgajbhiye4968]

ty very much sir

[@kirankumar-qo6lb]

thank you sir...
