| | | | | | · During the routine inspection of the microstructure of a low carbon steel sheet 1.9 mm of thickness, produced by high temperature rolling of a continuous casting slab, 50 mm thickness, the formation of superficial coarse ferrite grains was observed. A strong decarburization on the surface of the steel sheet was developed after the study of the a-Fe recrystallization behavior during annealing treatments, and the analysis of the dissolution behavior of the cementite. The presence of the coarse ferrite grains was related to the high temperature recrystallization process and the slow cooling during of finished and coiled of the steel sheet at high temperature. Since the decarburization was not uniform, a mixture of fine and coarse grains of ferrite was developed on the surface of the sheet. The decarburization of austenite was observed between the rolling steps, which results in a fine microstructure of a-Fe grains.
