Influence of severe plastic deformation bz the ECAP method on structure and properties of the low carbon steel
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. 290oC. 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 dislocation density and a small fraction of spheroidised carbides, which occurred usually at the ferritic grain boundaries. It was established with use of the EBSD technique that after 8 passes through the ECAP die the sub-grains with misorientation angles smaller than 10o formed less than 20% of the final structure. Average size of ferrite grains with high-angle boundaries after 8 passes was approx. 0.32µm.
