Go to the link and read the rest of the story. There is martensite, bainite, austinite and carbides all in the structure.................
I saw that. It still sounds strange, becuase austinite only exists in plain steel in the gamma phase. Room temperature austinite is only seen in tool steels.
If the speed if the trick then why haven't we see this in heat induction and water quenching?
I'll follow this one. Thanks!
