Question
Please explain! Thank you
The graph shows the isothermal transformation diagram for a coarse-grained, plain-carbon steel of eutectoid composition. Samples of the steel are austenitised at 850 degrees C and then subjected to the quenching treatments shown on the diagram. Describe the microstructure produced by each heat treatment.
