Abstract

The effect of deformation in the intercritical temperature range on the phase composition, structure, and properties of low-alloy steel of type 08G6N2MAF is considered. It is established that the deformation increases the stability of secondary retained austenite, provides a fibrous structure, and improves the mechanical properties of the steel. The special features of texture formation under different deformation temperatures are described, and the role of the structural components in the evolution of mechanical properties is discussed.
