Consider the following statements regarding the TTT curve,
1) TTT Curve is also called an isothermal transformation diagram
2) In the TTT diagram, the hardness increases in the vertically upward direction.
3) When Eutectoid steel is rapidly cooled from the austenite phase to less than 100° temperatures, martensite will be formed.
4) TTT curve explains the transformation of austenite in non-equilibrium conditions.
