Abstract

In the process of bending of 10KhN4MFA steel flat-bulb profile, grain boundaries break down, brittle fracture of specimens takes place, and steel toughness decreases at a degree of deformation of more than 3% and heating by high-frequency currents of the deformation zone to the hardening temperature (960°C). There is no brittle fracture of the profile in the entire range of the degree of deformation when the heating temperature of the deformation zone raises to 1050°C.
