Thank you so much for all your fascinating videos! I'm actually preparing for my phase diagram final tomorrow, and with just an hour or two going through your videos made me understand so much more than I ever did. These videos are straight forward, down to the point, and I can really feel your passion from them!! It was really fun to learn through them, after this final I might as well check the polymer part just for the funzies of knowledge!
Your videos are really helping me in my work with archaeometallurgy, where I reached a point at which learning some materials science has become necessary to progress. Thanks a lot.
Heck ya! Do me a favor and like/sub/share to help me keep making these videos. You might also consider leaving our materialism podcast a review on itunes. I would super appreciate it.
Came across this very interesting video by accident. Great explanation. I wanted to thank you for using celsius, it breaks my brain when Americans use fahrenheit in science/engineering fields.
@@TaylorSparks a while back I got myself into the lockpicking hobby. The picks (which are expensive for how tiny they are) fatigue over time then snap and/or bend. I was wondering if I could put the bent ones through a heat treatment and make them closer to new. Or could I undo some of the fatigue before they break. Because of how thin they are they quench instantly, I drunkenly tried doing it with a butane torch, quenched it but couldn't be arsed to anneal it. So of course it snapped immediately the first time I trick to pick a lock. Do you think there is an approach that would work? What sort of temperatures and timings should I be experimenting with? Cheers mate.
Actually, Pearlite and Bainite are very different in terms of microstructure. Pearlite has a alternate lamellar alpha-Ferrite and cementite structure which is not a mechanical mixture of both. But in Bainite, it is a mechanical mixture of alpha-ferrite and cementite instead of a lamellar structure. It’s like a colloidal solution of alpha-ferrite and cementite.
Super cleared explanation ! Mr Taylor, how do you really get the isothermal holds diagram to craft the TTT diagram for an specifict steel alloy by using the avrami´s equation? Is it get it by experimental methods? or is there some theorical method to predict them with regarding to ther alloying elements (wt%), Thank you!
@@zhengpakho technically no. martensite is a name for a structure in general and it can be found in different materials so its not specific to steel; austenite on the other hand is a specific name for a phase of steel. for steels: if you heat the material above Ac3 line(minimum point of Ac3 line being 723°C for eutektoid steels(eutectoid steel= iron with 0.8w% C)) you go into austenite phase but remember that its only stable above this temperature. so if you want to have austenite steel in room temperature its a bit more complex but can be achieved by using austenite-phase-stabilizers and specific heat treating

Thank you so much!!! I love to teach materials

@@landoonline6393 well, that sounds like an awesome research field.
your videos are fantastic. you are an excellent explainer, and I love your mustache.
Ha! Thank you! :{
This really was the best video on any topic I've ever watched. Love your channel, you help me a lot.
Heck yeah! Glad that it was helpful
These videos are just too good. The best explanation for all videos.

Lol. Too true! We heathens using Fahrenheit. So ridiculous! I wish we would just switch over to metric once and for all!

Awersome Video, watched a couple of videos on CCT and TTT diagrams and this is byfar the best . Thanks Taylor
Gracias homie
Wow what an amazing video, so much I understand in such a small amount of time.
This makes me feel, that I can pass my exam thanks man, beautiful work ❤
Wow this is a great explanation of these diagrams. Thank you for making this.
Your videos are super helpful and well done, using them to study for my matsci midterm this week. Thanks Prof!!
It's my pleasure! What are the videos would be helpful?
you teach way better than my teacher.
Amazing videos, my final is tomorrow and these helped a lot.
your channel will become known sir. thanks for all.great things take time sir. thanks thanks thanks thanks
Spread the word! We also have a podcast "Materialism"
you are better than my professor tbh thanks!
so glad to help! help share the vid and channel to help me grow ;)
thank you, great video!

Thank you! I agree, it's an oversimplification that I present here, but it's also an intro to MSE course.
Great explanations!
Really good explanation.

Nice explanation
love you for this!
My pleasure!! My channel has loads of great mse content. Enjoy!
Sir, how can one get fine pearlite from martensite? Thanks in advance
reheat the martensite so that it will transform into austenite(gamma phase) and then cool it down again but this time slower.
@@stopstalkingyouspookybastard Thank you. Does reheating martensite always gives austinite?
@@zhengpakho technically no. martensite is a name for a structure in general and it can be found in different materials so its not specific to steel; austenite on the other hand is a specific name for a phase of steel. for steels: if you heat the material above Ac3 line(minimum point of Ac3 line being 723°C for eutektoid steels(eutectoid steel= iron with 0.8w% C)) you go into austenite phase but remember that its only stable above this temperature. so if you want to have austenite steel in room temperature its a bit more complex but can be achieved by using austenite-phase-stabilizers and specific heat treating
