Structure and properties of low carbon steel after severe plastic deformation
Original language description
The article presents results of investigation of structure and properties of low-carbon steel after application of Equal Channel Angular Pressing (ECAP) at the temperature of approx. 290°C. The ECAP method lead to significant improvement of strength of investigated material. Investigation of structure was made by combination of TEM and FEG SEM together with EBSD. It was proven that the ECAP method enables obtaining of ultra fine-grained ferritic structure formed by re-crystallised grains with very low density of dislocations and small portion of spheroidised carbides, which occurred usually at the boundaries of ferritic grains. It was estab.lished with use of the EBSD technique that after 8 passes through the ECAP die the sub-grains with an angle of disorientation smaller than 10° formed less than 20% of resulting structure. Average size of ferrite grains with high angle boundary after 8 passes was approx. 0.32mm
