The steel phase diagram

No phase diagram is more important to materials scientists than the Fe-C phase diagram because it allows us to explain many of the different types of steels. The key area of the diagram is the eutectoid below which austenite converts to ferrite and cementite. The proeutectoid ferrite or cementite that forms will be surrounded by pearlite, bainite etc.

It took almost 2 days for me just to able to point out basic terms but you taught this whole equilibrium graph in such short time...Hats off

[@TaylorSparks]

Heck yeah homie!

You make the subject comprehendible and interesting. Two in one prof, thank u so much

[@KaiserBruh]

thank goodness i found this video. finally someone that explains everything flat out. thank you sir

[@lolerdielolol]

Amazing! with one quick video you fill up all my gaps I had in understanding it, thanks!

[@TaylorSparks]

Glad to help! Check out the Materialism podcast. Our first episode is on the history of steel. Very cool stuff.

[@ABDULAHAD-tg3ke]

Made it comprehendable ! You are really a champ Prof❤

[@lazarblazar265]

Never thought i would be able to understand these phase diagrams (equilibrium ones) with less difficulty. I remember i used to gasp when i saw them for the first time years ago haha

[@SF-oq1qx]

Wish I had him in all my chemistry classes. Amazing!

[@phenomenal821]

Wow, I never taught I would understand Fe-C phase diagram to this extent. Thanks alot prof, I am really grateful for this video. Pls can you do a video on crystallographic projection, I can't seem to find it on KZbin.

Great explanation sir

Great explanation, was very difficult to understand in my textbook.

hey i want to know the microstructure of the eutictic below 727 and thank you verymuch

[@TaylorSparks]

How is it cooled? If slowly then it will be lamellar at first but these will coarsen towards spheroidite if given long enough

[@edran4449]

is there a playlist for this?

[@edran4449]

it would be very helpful cause i cant understand my lecturer and youre the only person that i understand

[@andrewarner557]

So if we exceed the third phase whilst under extreme pressure?

[@TaylorSparks]

What third phase?

[@omidyourdkhani1184]

nice sir!.. how can i have those text files?

[@TaylorSparks]

The course notes?

[@laprepper]

What a weird naming convention that it goes iron, steell, cast iron. I feel like a better convention would have been iron, cast iron, then steel, or maybe iron, steel, cast steel. Is there a particular reason the naming convention turned out how it did? At any rate great video with lots of valuable content, I'm going for a position and material science without any experience that I'm trying to brush up on my metallurgy.

pnc.st/s/materialism/78772fdfaffa4a56/the-history-of-steel Actually we cover it in our very first episode of the materialism podcast! Steel is such an incredible material.

what is a bainite ?

[@obadiahdadzie3056]

You have any youtube channel for only questions?

[@TaylorSparks]

Many of the ideas for videos come from questions raised here in the comments section. Were you thinking of a live q&a? Or did you have just a specific question you wanted answered?

[@obadiahdadzie3056]

@@TaylorSparks I thought you had a separate channel for solving examples on the various topics..I’m much interested in the Fe-Fe3C system

[@TaylorSparks]

@@obadiahdadzie3056 I have a playlist with worked example problems. What question did you have in mind?

[@obadiahdadzie3056]

@@TaylorSparks Awesome..I have no question in mind I just want to solve more examples because I’m done studying the content and I have exam this coming Monday

[@ayeshaarshad1036]

is austinite harder than ferrite?

[@TaylorSparks]

I've never seen it reported... But ferrite is BCC and austenite is FCC. FCC has way more slip systems and tends to be softer. Austenite is also stable at high temps where you typically see softening. So I would guess ferrite > austenite.

thanks

[@duzgundiyartop201]

Thank you for such a good video. I appreciate it, but this materials science really sucks you just need to memorize everything :(

[@TaylorSparks]

Nah, they need to explain it from the basics point of view. Once you understand the fundamentals you can derive everything so you don't need to memorize it.
