Description: An example of a hypereutectoid steel (one that has a carbon composition above that of the eutectic). Upon cooling from the austenite field, the first phase to form is cementite on the austenite grain boundaries. This partitions iron and at the eutectic composition pearlite is formed from the remaining enriched austenite.
