Segment 2 of Lecture 8. Steels and the Fe-C phase diagram. Course webpage with notes: dyedavid.com/mse104 Lecturer: Dr David Dye. Licence: Creative Commons Department of Materials, Imperial College, London, UK
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.
Greetings. I am a amateur part time bladesmith with an interest in Metallurgy as a result. I've been reading books, watching TH-cam 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.
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
very good teaching. i have only one problem with it. could you not make those "eh" "um" ..... sound? and you will be perfect! ( sorry im blunt but no offense )

Hi is there a zoom in version to the eutectic point ?
doesnt eutectic also refer the change in the melting point or am I missing right in front of me ?

could you please make a video on fracture!
I just want to be friends with this guy :(
you saved my exam
tribute from civil engineering
COOL
