    The microstructure is predominantly martensite but also has allotriomorphic ferrite, Widmanst228;tten ferrite, bainite and pearlite. Notice that the spherical shape of a pearlite colony is obvious in this sample because of the lack of impingment. Notice also that pearlite, unlike bainite, grows across the austenite grain boundaries.
