I want to learn how to apply this law to data obtained by moisture absorption experiments.

Is there an example solved for fick's law? How do you calculate it for some material?

Why twinning happens

Hello Sir. Hope you are fine. I have a doubt in this lecture. At the time when temperature of the outside surface will be just above Ms, the temperature of inside will be quite higher (somewhere around nose or above nose). If the quenching of specimen is interrupted here and temp is kept constant, the curve of outside will definitely follow the non-transforming region, but the curve of inside will cross the transformation region and hence may transform into pearlite. Sir it's a request to clear this doubt because I am preparing for my exams.

Same rule apply to fcc can we say Nacl is not fcc??

So two different crystals one where Cs at corner and one in Cl at corner and arranged such a way that Cl at body centre and Cs at body centre

Very informative

👍👍👍👍

is it the potential energy of the system that is decreasing? Because according to the law of conservation of mechanical energy if an isolated system is subject only to conservative forces, then the mechanical energy is constant.

No one in the world they never teach like you

👍

Finally completed Material science series for ISRO Scientist Interview Prep. ❤🎉 Great Journey by the way. Thanks professor 🔥✨

If creep is considered a high temperature phenomenon, how is it a factor of glacier movement?

In martensitic transformation the amount transformed is dependent only on temp not on time

1. Advantage of TTT diagram over Iron-Iron carbon diagram - Has time axis 2. Disadvantage of TTT diagram over Iron carbon diagram - TTT diagram for only single composition

Why coarse grain in annealing and fine grain in normalising 19:20 -Annealing occurs at higher range of temperature and Tempering occurs at lower range of temperature. - At higher temperature I. E. Annealing - growth rate dominate nucleation, so coarse pearlite are formed - At lower temperature I. E. Normalising - nucleation dominate growth rate, so more nucleation occurs than growth, so fine pearlite formed.

Why C curve? 11:12 to 12:57 -Initially (near TE) Driving force is less but atomic mobilisation is high -Finally (near T=0C) Driving force is high but atomic mobilisation is very less

truly a gem for any materials science student

what a creep

Thank you very much sir, i would love to ask a question Is this all one needs to understand concerning flicks law?

how can liquid exist below its freezing temperature i mean by that time everything would have been converted solid itself right how will nucleation occur below Tm as what i understood was freezing will occur till complete liquid changes to solid and until then T will remain constant at Tm

Very nice explanation, thanks

@24:72 this fraction is valid only at that particular temperature right .i.e, the lever should be made corresponding to the equilibrium temperature in question right?

Tank you sir 🎉

What will be quenching temperature?

Thank you so much sir 🙏🏼

Great explanation, thank you sir. I got to understand fatigue better

Best lecture ever in NPTEL on material science and engineering

Спасибо. Очень наглядно и понятно. Один только вопрос - если в роли матрицы будет выступать композитный полимер, выплавленный из LFT-G -гранул (композитные гранулы с длинными волокнами углерода/базальта/стекла), а в него будет добавляться керамический нано-аддитив по типу нитридных или карбидных нановискеров, то это будет гибридный нанокомпозит с несколькими фазами (нано- и макро-фазы)?? Или же это будет полимерно-волоконно-керамический нанокомпозит, как пример GFRP-LFT-G-nSi3N4 (матрица - сплавление в лист гранул LFT-G TPU/RTPU + LGF, а добавляемый наноаддитив - нановискеры нитрида кремния)?

God tier ✅

This video blew my mind, will understand it slowly over time.

thank you sir

Come on Paul, let's play with the Buckminster Fulerenes.

Wow! thank you sir!!! May God bless you!!

Sir, why volume constancy is valid in plastic deformation ?

I want to be a jet engine engineer that’s why i am studying hard hope i can make it🙏🏻

Thanks professor

Nice explaination on Nacl . Thanks sir .

8:25 "Armstrongs seems to be quite headstrong " 😂😂😂

I have made two mistakes in this video : 1. I have considered Trigonal and Rhombohedral as synonyms for the same crystal system. However, as per the International Tables of Crystallography Vol A it.iucr.org/A/ the two terms are NOT synonymous. Crystal System should only be called Trigonal and not Rhombohedral. 2. I have shown only one Bravais lattice in the trigonal crystal system. But in reality there are two Bravais lattices in the trigonal system: hexagonal prinmitive (hP) and hexagonal rhombohedral (hR). And so there is no trigonal P Bravais lattice as shown in the table in this video. I plan to make a video to clarify this. Wil share the link once I do it. You can check en.wikipedia.org/wiki/Crystal_system.

Iam student of NIT Jamshedpur Also my professor coppied your teaching material thank you sir for providing this complete course

Do you just draw the tie line on how and anywhere?

13:56

Thank you Sir. Which book you recommend which covers all of “introduction to Material sciences “ chapters in a same easy approach??

Sir u cleared my all doubts. Infact i didnot get this much knowledge by reading rolfe and barsom. Hats off to ur explanation

Thank you so much Sir❤ you made it easy 😊

What is free surface?
