Abstract
Electron Backscattered Diffraction (EBD) technique was employed to study the relationship between grain boundary sensitisation and grain boundary types present in nitrogen-added AISI 316LN austenitic stainless steel heat-treated at 800 °C, varying time at this temperature in the range of 1 minute to 100 hours. In comparison to the basic state no changes neither in grain orientations nor in grain boundary types were observed. Twin boundaries were found in all samples with the highest frequency and only small occurrence changes. CSL designation mode also showed only little influence of heat treatment on distribution of CSL boundaries present. Additionally, on the base of misorientation measurements of 50 grooved boundaries, a preferred attack of high angle boundaries (30-55°) was noted.

Key words
austenitic stainless steel, sensitisation, EBSD, CSL boundaries
