Microstructure and Impact Toughness of High-Strength Low-Alloy Steel after Tempforming
The effects of temperature and degree of tempforming deformation on the microstructure and impact toughness of high-strength low-alloy 25KhGMT steel have been considered. Tempforming forms a lamellar microstructure composed of grains and subgrains that are strongly elongated along the rolling direct...

| description | The effects of temperature and degree of tempforming deformation on the microstructure and impact toughness of high-strength low-alloy 25KhGMT steel have been considered. Tempforming forms a lamellar microstructure composed of grains and subgrains that are strongly elongated along the rolling direction. The average size of the grain section is 570–790 nm. Deformation texture includes 〈001〉 || ND and 〈111〉 || ND fibers. Tempforming increases the fracture work of this steel at lower test temperatures (
KV
–40°С
≥ 360 J) due to the delamination of the specimen perpendicular to the impact direction, which prevents crack propagation towards the direction of the impact. |
