It represents the non-equilibrium transformations (pearlite, bainite and martensite) that can take place in the isothermal cooling of the austenite of an eutectoid steel. The influence of time and temperature on the transformation of austenite is indicated. In the vertical axis the temperature is represented and in horizontal the time in logarithmic scale.
