Effect of Severe Plastic Deformation on Structure and Properties of Austenitic AISI 316 Grade Steel

Co-authors GREGER Miroslav

Article presents results of investigation of structure and properties of austenitic AISI 316 grade steel after application of ECAP technology. ECAP method leads to significant improvement of mechanical properties. Detailed investigation of structure evolution was made not only with use of Transmission Electron Microscopy (TEM), but also by Scanning Electron Microscopy (SEM) in combination with Electron Backscattered Diffraction (EBSD) which enables characterisation of misorientation angles of individual crystallites on the surface of metallographic sections. Effect of thermodynamic stability of structure has been also investigated.
