Summary:Title screen
The effect of uniform isothermal forging (UF) and warm rolling (WR) on the structure of low-carbon tube steel 12GBA has been studied. It is shown that the structures of the treated steel differ significantly by the effective grain size, density of all boundaries, percentage of density of high angle boundaries (HABs) and low angle boundaries (LABs), carbide phase morphology in the perlite zone and texture of the ferrite phase. After forging steel has the greatest degree of grain refinement, maximum boundary density, and overrepresentation of LABs. This structural state of steel is characterized by a double-component texture: (001) + (111), <001> + <101>, while after warm rolling steel has a monocomponent texture (111) <101>. The evident differences in the steel structure treated by WR and UF may have dual effect on the strength and plasticity properties of steel and its fracture behavior.
