A steel, possessing an eutectoid composition, undergoes a gradual cooling process from 800°C to
600°C. Outline the transformation, equilibrium microstructure, and provide approximate component
proportions.
Describe the resultant non-equilibrium microstructure in two scenarios:
a) the steel is rapidly cooled from 800°C to 600°C within 1 s, and then held at such temperature;
b) the steel is rapidly cooled from 800°C to 600°C within 1 s, maintained at this temperature for
5 s, and subsequently quenched to room temperature.
Use the provided diagrams.
