Why the material crack while heat treatment?

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.

Hardness of steel depends on the carbon content bro, generally cementite is the hardness factor. Martensite means the dispersion pattern of cementite in austenite.

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

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.

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.

​@@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.
