4.2: TTT diagrams and phases in steels (pearlite, bainite, martensite, and more)

Wow! Exactly what i was looking for, took a bit of time to figure out the specifics but nice informative video!

This is what, I was precisely looking for. Finally found amazing piece of information with lot of contents, 👍

The traditional Japanese sword makers coated the sword in a clay mix on the back of the blade (the blunt side), and left the sharp side uncovered. They heated the sword and judged the right temperature by the colour, then quenched it. The sharp edge had no clay on it so it cooled immediately, the spine of the blade had clay on it so it cooled much slower. The end result was a sword with a tough flexible spine and a hard sharp edge.

Can you give me the link of website please?

I thought austerity couldn't exist at a temperature below critical temperature, how is it existing at 300 degree Celsius

OK but pearlite/spheroidite etc are structures/microstructures, not phases. Bit of a semantic thing I guess but phases are defined only by their atomic structure/composition, nothing above a few unit cells' length matters for the phase. But the same phase/phases can have very different properties depending on their larger scale structure.
