Time Temperature Transformation curve and its significance is discussed in tamil. It will help you understand the concept behind the heat treatment processes of steel.
TTT curve gives the details about the isothermal transformation that occur at various temperatures with respect to time.
The change in microstructure, austenite to pearlite or Bainite can be observed from this curve.
Heat treatment processes are very important in the field of production engineering.
Excellent.. excellent.. excellent teaching. You have deep knowledge in all subjects. Very big salute to your knowledge. At the age of 60 lot of doubts cleared. 👍👍👍

Very nice sir.
Waiting for next video
Thanks for your help anna
Apo nama room temperature elam Eutectiod steel um martensite aa bro , also as per iron carbide phase diagram room temperature la elame alpha ferrite and cementite aa? Then how ductile materials are produced plz explain me bto
Good lecture
Super bro , neenga enga college vandhrunga bro
6.39 mins Full clear view diagram , Thank me later
மிக்க நன்றி சகோ.
Super sir 🥰
Sir one doubt is iron carbon diagram is also called binary phase diagram??
Actual cooling rate and critical cooling rate pathi oru video post pannunga pls
Super sir🖤
Brother can you explain the CF8M heat treatment process, please
Super sir
Ji thanks ji naan railway la velai pakuren..ithubimportant anana concept...ji nan training lan irukekn ji
All the best bro
Metallurgy series full ah lecture video podunga bro
Thank you sir
Sir hardness increase aaguthunu sonnenga but athu kila varuthe so decrease aaguthunu thaana consider pannanum
Thankyou sir
Thank u for clear explanations. U here said that ductility and hardness related to change of cooling so like that remaining properties of steel such as brittleness and toughness and malleability etc related to which one increase or decrease? Could you explain this? If u tell this it’ll finish heat treatments concept 70 percentage
Hi bro Toughness and yield strength of steels can be improved by cold working process like cold rolling etc.. Increase in hardness will increase brittleness.
100 % Engineering : thank u. Before complete heat treatments u could teach properties of materials which involves in heat treatments be practical approach then only listener can understand all questions to do answer. Once again I request u that what kind of question comes from this material part? If you crack this ideas after taken a class ( topics) definitely candidates never miss the Question to answer 👍 thank you 🙏
K bro sure I will work on that. Thank you for the valuable suggestions bro.
Why the material crack while heat treatment?
Nan 2nd year la metallurgy padikumbodhu ipd paathurundhana kandipa Purinju padichirupen..

Sir type of cast iron video Pannuga sir
Thank you Sir ❤️
Welcome!!
Itha eutectoid iron carbon steel nu solalama
hi sir can give sequence for these material science videos
Sir when is the next video
👌🥳
How Austempering is covering into 100 Percentage Bainite in Transformation . Could you please explain
We will see to that during the heat treatment processes one by one
Bro Continuous cooling transformation video podunga
Sure 👍
beo microstructure ah epudi identity pannurathu nu video podunga bro
Need CCT diagram explanation pls..
7 phase diagrams um nadathunga .it will be easy for us to understand
Will try
Bro neenga draw panna diagram Mathiriya na draw pannlama
Bro will eb privitization ?? So tneb AE exam will conduct or not, if privatization will affect the exam and vacancy??
Maximum tneb privatize panna matanga bro.
@@100Engineering thnk u bro
heat treatment online class iruntha solluga please
Sir next video
Grain Size na Enna?
Sir is this lectures are enough for isro scientist exam ??
Yes
Hardness of the steel depends on martensite or cementite bro
Hardness of steel depends on the carbon content bro, generally cementite is the hardness factor. Martensite means the dispersion pattern of cementite in austenite.
SIR, Can u explain HEAT AFFECTED ZONE (HAZ) characteristics in WELDING?
Hi bro, welding chapter paakum podhu explain panren 👍👍👍
@@100Engineering Thanks bro , Welding Metallurgy explain panunga bro.
Sure bro this we will discuss while seeing the heat treatment processes
@@100Engineering Thanks sir
Unga teaching super Anne👏🔥

Plz put next video sir
Sorry for the break, I will try to upload soon
Sir, Need aluminium silicon phase diagram in tamil
As soon as possible
Bro inu konjam tamil ha pasugaha broo
Cleary understood
Your correlation between grainsize of steel and cooling rate from hardening temperature is not correct. Grain size is controlled only from steel manufacturing. If you really want to control grain size the austenizing temperature and holding time at hardening temperature matters. Your teaching method is excellent but the matter seems insufficient.
Thank you for writing. Will improvise in upcoming videos
Grain size na ennanga sir
Particle size
@@100Engineering partical size means atoms and molecules structure nga sir?
Particles consist many molecules
@@100Engineering thanks sir
Videos are not in proper order. How to draw TTT diagram? How did you draw that? Even your previous lectures were also in same manner. Though much qns will not be asked over Materials science in TRB, things should be completely learnt and taught. My kind suggestion. Elathayum solitu TTT diagram epdi vandhuchu nu solalaye. Isothermal transformation concept miss panitinga. Inum neraya iruku athula ungalukae terium. TRB kaga naa, just important mcq solitu muduchurunga bro. My suggestion to you. Let Your beautiful work on motivating others be continued. Thanks bro.
Hi bro thank you for your kind suggestion. I strongly believe that my videos will help people understanding the concepts. Enaku therinja madhiri teach paniruken. Its not much easy to explain things without students infront of you. If possible TTT diagram epdi teach panlam nu oru video enaku suggest panunga. Am not doing this just for TRB. I want to teach whatever I know. My motive is something big.
And moreover I'm having limited resources to make the videos. So I'm doing the best I can.
@@100Engineering First of all, a very big congrats to you for the motivation you hold. Yes , it is not as easy as learning. Thats why , it is not easy to cover all the topics in a single video unless otherwise keenly prepared. Sorry , you said these are not only for TRB then You have to take more steps to explain the concepts in precise manner of each and every subject. Why should you need students infront of you to explain things? I have no idea about this but still from my opinion .Enthusiasm makes one work more on that, it wont search for the reasons for learning from mistakes. I meant that how did this TTT diagram take S or C curved shape? Have you first think of it? You came prepared infront of your board. You have to answer and shouldnt question me. (Im extremely sorry for my words and nothing personally to hurt you. just think and act bro. So many of people are wishing you and they mean you for your invaluable work. Teaching is not about whatever you know , its all about what you have learnt. May your motivation grows bigger than you aimed.
I'm not hurt bro. As you said am not questioning you as well. I would like to know how better I should have explained it so that I could do better in future. And I'm not finding reasons as you said. I take videos by sacrificing my sleep.I'm really doing it with great passion. I will come up with more precise information in our future videos. Teaching ku interaction than bro basic tool, that's y I mentioned it's not that easy to teach infront of a camera. Thank you so much for your valuable suggestions. Keep supporting keep suggesting.
Neenga solra enthusiasm ellamey enakum iruku bro. Ilama idha nan seila. But enoda situation enanu ungaluku theriyadhu. I just love teaching. Neenga solra madhiri videos podradhuku neraya time venum bro and proper tools and resources kandipa venum. Kandipa future la videos innum theliva podlam bro.
Thank you sir
