Surface contamination and loss of surface smoothness are common issues encountered during in-situ tensile tests in scanning electron microscope (SEM). To overcome these limitations, microstructure and texture evolution by tensile deformation of an austenitic stainless steel was studied by sequential tensile deformation in a tensile testing machine and SEM examinations. After each tensile deformation step, the contamination due to the preceding SEM examination and the roughness caused by the deformation were removed by a light polish. SEM examinations consisted of electron backscatter diffraction (EBSD) and electron channeling contrast imaging (ECCI) of grains with different crystal directions parallel to the tensile direction. EBSD results allowed to represent the evolution of the crystal axis parallel to the tensile direction by arrows on an inverse pole figure. Furthermore, the tendency of grains with different orientations to exhibit wavy or planar glide features, in particular deformation twinning, was evaluated by EBSD and ECCI examinations.
