Abstract

Research using electronic microscope was carried out to study the structural and phase and deflected mode of material of hot-forged billets. It was revealed that the scalar density of dislocations in ferritic grains and in ferritic perlite layers of forging steel which cracked after manufacturing operations is one and a half time higher than in conditions material. Metal in this condition has higher content of sulfide of plate-type morphology. It has established that the reason of unwanted structural and phase condition is high carbon content, which lead to overheat of metal both in plastic working and final heat treatment.
