This thesis focuses on the nanostructuring of steel using Equal Channel Angular Swaging (ECAS) – an innovative process for the continuous formation of ultrafine microstructures through severe plastic deformation. The aim is to compare the achieved material properties with those obtained by other forming and SPD processes and to analyze in detail the relationship between process parameters, microstructure, and strength.

Through targeted material selection, forming experiments, and metallographic investigations, the potential of the ECAS process for producing high-strength yet ductile steels will be evaluated. In addition to microstructural refinement, the industrial scalability of the process will be assessed. The results will contribute to a deeper understanding of process–structure–property relationships and support the further development of advanced forming technologies in materials engineering.
