... is called proeutectoid ferrite because it forms prior to cooling through the eutectoid temperature. This is in contrast to the eutectoid ferrite that forms at the eutectoid temperature as part of the constituent pearlite. While cooling the alloy through the α + γ phase region, the composition of the ferrite...
