Выдержка

An electron microscopy investigation of structural-phase and stress-strained state of a hot-forged material workpiece is performed. It is found out that the scalar dislocation density in ferrite grains and ferrite interlayers of pearlite of steel from the forged piece fractured after technological processing is one and half times higher than that in the commercial material. The metal in this state has a higher content of sulfides of lamellar morphology. The volume fraction of pearlite in it is 1.5-2 times larger, with the lamellar pearlite prevailing, and the local long-range stresses being comparable with the yield stress. It is found out that the reason for formation of an unfavorable structural-phase state is the elevated carbon content, which resulted in overheating of the metal both during pressure treatment and final thermal treatment.
