Further information
Low carbon steel. The resulting microstructure is therefore virtually all of the ferrite phase, since upon reaching the eutectoid temperature virtually all of the austenite will have transformed to ferrite. This sample is taken from the bottom of a wood screw, some directionality is observable due to the item being rolled.
