Formation of Ferrite, Cementite and Pearlite in Eutectoid Steel

engineers.academy/
This video introduces the phase diagram for steel, which enables us to determine the phases present within steel at different temperatures and compositions.
After learning how to read the phase diagram, you will be shown how to determine the Eutectic and Eutectoid points, compositions and temperatures for plain carbon steel. You will also learn how Ferrite, Pearlite and Cermentite form from Austenite in steel's with different percentages of carbon content.

Very good document of steel microstructure tranformation. Thank you

[@Dreams__one]

Well played, really well done and explained !

[@FatmaTaha-bo8js]

Well explained 👏 many thanks 🙏

[@JCQuadcopters]

Thankyou! Life saver

[@tahy59]

much better than college professors

you said Ceramics have a very high tensile strength in around the 11th minute in the video, how can this be when ceramics have low tensile strength because of the presence of cracks and very high compression strength. can you clarify what you meant when you said that?

Could you tell me what the Gamma and Alpha mean when you say e.g. Alpha Fe3C + Gamma? I love the video though. Very well explained.

These are the different phases of the steel (or Iron). Alpha is body centre cubic (BCC) and exists at lower temperatures, whereas Gamma is Austenite and is the steel phase at higher temperatures, when it turns to face centre cubic (FCC). FCC is softer and more malleable than BCC.
