8.2 | MSE104 Steels & the Fe-C diagram 

Being an American from the deep South, when I heard his British accent I knew this was going to be a good night. My entire study group sends a thank you from across the pond for posting these videos. Hopefully we'll pass the test in the morning.

Get this man a beer

Thank you for taking the time to post these lectures. Very helpful!!

I love all you're explanations. Thank you very much.

Powerful lecture Delivered well 😊😊

wish you were my teacher

thanks a lot for this, David! Helped me out a lot

Greetings. I am a amateur part time bladesmith with an interest in Metallurgy as a result. I've been reading books, watching RU-vid videos and asking many questions, Professors from Canada, India, the UK, Germany and USA. However, I find two-schools of teaching out there. One group teaching that the Eutectoid temperature line A1 is at 723°C and the other at 727°C. Then one group teaching that the wt%C at the eutectoid point is 0.8% and the other teaching 0.76wt%C. There are some other differences in the two different groups of teaching that I will not go into now. I am somewhat confused to why there is a difference. If we are talking about pure Iron Carbon, there should be no alloys in the steel to make a difference. Could you please shed some light on this for me please.

was very helpful.... did not have the the patience to go through books..:) thank you

doesnt eutectic also refer the change in the melting point or am I missing right in front of me ?

I'm kind of confused at this point. Isn't that the Fe-Fe3C diagram (K instead of K', Austenite-Fe3C instead of Austentite-Graphite etc.)? At least that's the seperation they keep making at my university here in Germany

This was really helpful, thank you for explaining.

Hi is there a zoom in version to the eutectic point ?

Bravo sir..u made my day..❤

Thanks much, helped me a lot.

Thank you so much for this :)
