Abstract

The paper presents an electron-microscopic analysis of structure, phase and stress-strain state of forging material. It was found out, that dislocations in ferritic grains and pearlite layers of forgings, cracked after manufacturing processes are half as large against those in standard material. Metal in this state is characterized by an increased concentration of lamellar sulfides. It is also stated that disadvantageous structural state is formed due to high concentration of carbon which causes metal over-heating both when forming and in final heat treatment.
