EBSD characterization of a hot worked 304 austenitic stainless steel under strain reversal

Monotonic and strain reversal hot torsion tests were performed on a 304 austenitic stainless steel, this led to changes in microstructures depending on the strain path. electron backscatter diffraction was used as the tool for characterizing the microstructures. It was possible to find some intragranular microstructural changes due to the reversal of the strain by means of several local and global misorientation-related parameters. Σ3 boundaries also showed sensitivity to strain reversal.
