Hello, I am wondering how I could create only ferrite and martensite from a hypoeutectoid plain carbon steel. I am looking at the TTT diagram, and I don't see how this can be done. If I quench to create martensite, and then temper it I will have ferrite and cementite. I don't see how I could separate the ferrite from the cementite. I don't see pure ferrite anywhere on the TTT diagram, is it a metastable phase that is not shown? Also, is it possible to create pure ferrite from austenite?
