Dear All,



Material : Carbon steels in between 0.008% carbon and 6.67 % carbon.

1.Is there any metallurgical changes(phase change) will occur other than pearlite,if I heat rapidly uncontrolled heating)low carbon steel just below or equal to lower critical temperature(723 C) as per iron-carbon equilibrium diagram?

2.1.Is there any metallurgical changes(phase change) will occur other than pearlite,if I cool rapidly (uncontrolled cooling, no quenching by any kind of liquid medium)low carbon steel from just below or equal to lower critical temperature(723 C) as per iron-carbon equilibrium diagram?
