This makes things a bit clearer than they were in class.

This is one of the topics Khan haven't made yet. The definitions you give is really great. Speak slow and precise. Thanks.

Very clear and straight to the point explanations. Helped out a lot 👌

You are very welcome! I'd like to do some stuff for Khan, especially for engineering, as they have stopped short of these topics.

Very good explanation. Thanks.

When you calculate pro-eutectoid ferrite, your tie line went passed the boundary (solidus). If instead your tie line stopped at the boundary, what would that indicate instead? Or does it not have any meaning?

thanx man.. u made my lide easier

very well explained thank you very much!!!!!!

Thank you so so much that helped out alot

thanks it helped me a lot

so helpful thanks

U saved me a lot of time You are awesome

thanks very very much

is this figure taken from W.D.callister??? :) but you have taught very well.. :)

THANKS!!!!!!!!!!!!!!!!

It was helpful. Thanks

Thank you Sir..

GOOD JOB

thanks a lot

for my question, it says consider 1.0 kg of austenite, is there a difference in the steps?

better than that spoon me video :#

never mind, but what does this say : Wα∙T=Wγ∙U ???

Where did 0.76 come from?

@katherinehiggins2861

percentage carbon at the eutectoid point

+Lene Fosse Thanks, Katherine. 0.76% is the point at which carbon is eutectoid in iron in this composition. It is shown clearly on the diagram, but maybe I should have stated it explicitly.

In part (a) you refer to it as the pro-eutectoid Ferrite. Is the Austenite you solve for technically pro-eutectoid Austenite in part (a) as well? Or is it not because the beginning microstructure is pure Austenite?

+Nicholas Volkenant "Pro-Eutectoid Ferrite" is in contrast to the "Eutectoid Ferrite". PEF is Ferrite made before the eutectoid point, whereas EF is made at the eutectoid point. Austenite is not developed at either point and is actually transformed into other constituents as the temperature drops. Thus, there is no "pro-eutectoid Austenite", nor is there "eutectoid Austenite" because Austenite is not produced in these locations (assuming a drop in temperature). I hope that helps.
