Texture development in 304LN austenitic stainless steel during post-hot-axisymmetric compression

In the present work, 304LN austenitic stainless steel has been considered for the texture evolution study after the hot-deformation process. The axi-symmetric compression tests, with post-deformation isothermal holding at the same temperature, were performed at 900 degrees C, 1000 degrees C and 1100 degrees C with a strain rate of 0.1 s(-1). Texture evolution during the post-hot-deformation was studied through electron back scattered diffraction. Effect of temperature and holding time on texture evolution were studied. At low deformation temperature and lesser holding time 100 and 110 fibre textures were observed. At high deformation temperature and/or high holding time the texture becomes random. Texture intensity along alpha fibre, for all the temperatures, is chaotic whereas along beta and tau fibres it is uniform at low temperature and becomes chaotic with the increase in deformation temperature. Goss component was found to be a major texture component with significant amount of ND and RD rotated cube components.
