Abstract

Deformation twinning has traditionally been studied with Transmission Electron Microscopy (TEM). In this study, an assessment of deformation twinning in Austenitic Stainless Steel (ASS), type 304L, cold rolled to 20% reduction was investigated using Scanning Electron Microscopy (SEM) and Electron Back Scatter Diffraction (EBSD) techniques rather than the conventional TEM. The study revealed the presence of deformation twins in the cold rolled grains of ASS. It emerged from the study that the deformation twins observed may facilitate localised heterogeneous deformation and development of internal stresses within the grain.
