Pleaseee make more videos in english....i could understand this subject better with your explanation, it is quite hard to learn in german

When you explained cooling of HyperEutectic system, you used diagram of Hypoeutectic system. It creates little confusion. However, commendable job.

Sorry, I don’t. There is a book Wiley Schnellkurs Werkstoffkunde, but unfortunately it is available in German only.

Frage bitte! womit läßt sich eine verstärkende Wirkung in einem umgebenden Material besser realisieren? mit dicken oder mit dünnen Fasern?

Good day Professor. As a hobbyist bladesmith I am teaching myself as much as possible about metallurgy to apply in this craft. However most KZfaq videos on the subject are from India. I have notice some discrepancies with regard to the Eutectic line, where some say it is at 723 deg C and others say 727 deg C. Another is the Curie line that I have seen differ from graph to graph as well as the Eutectic Point differing between 0.76% carbon on some and 0.83% on others. I am also unsure as to if steel actually loses its magnetism from the eutectic line until the Curie line or does this only happen at the Curie line? I would really also like to know more about the process, theory and differences of Normalization and Annealing especially for steels around the eutectic point i.e.just above or just below. Thank you very much for the English videos, as these are very scares thus highly appreciated.

I think the minor differences in the data you refer to are caused by how theoretical a graph is. If you want to actually apply these graphs into the real world, you'll need quite some extra knowledge to use them properly, since the graphs are made based on Gibb's free energy method, and thus show which phases should exist under certain conditions, in perfectly mixed, thermodynamical context. In reality it takes some additional energy to actually transform from phase to phase, that activationenergy depends on many things and can be quite tough to comprehend. I don't think it's gonna be easy to find all the knowledge to reason things like that yourself on youtube, but many people i the same brand probably do and can explain it to you personally, or they just know how it works, whatever the sciency behind it may be. These kind of video's is defineteley what you need to absolutely understand it, but it'll probably take a few dozens hours of lectures rather than just one.
