The effect of warm rolling (at 750 – 550°C) on the structure and mechanical properties of low-carbon steel 12GBA is studied in tensile tests in a wide temperature range. Metallographic analysis with the use of optical, scanning electron and transmission electron microscopy is performed. The strength and ductility properties are determined in tensile tests at from 20°C to –196°C. The suggested mode of warm rolling is shown to affect favorably the structure and the combination of mechanical properties of steel 12GBA.

Key words

warm rolling low-carbon steel cementite morphology texture strength ductility micromechanisms of fracture
