“…Taylor and Hodgson 24 observed the development of α fibre by axisymmetric compression of 304 austenitic stainless steel within the temperature and strain rate range of 700°C–900°C and 1–100 s −1 , respectively. In one of the earlier works of the present authors, 25 it was observed that the compression of 304LN austenitic stainless steel at 900°C produces 〈110〉 fibre texture, which diffuses with the increase in deformation temperature, and α fibre at 900°C. The texture evolution on high temperature axisymmetric compression of austenitic stainless steel, reported till date, are restricted to the deformation only.…”

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°C, 1000°C and 1100°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 α fibre, for all the temperatures, is chaotic whereas along β and τ 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.

To study the grain boundary misorientation change and texture evolution in austenitic stainless steel at low cold-rolling reductions, SUS304 austenitic stainless steel samples with a cold-rolling reduction of 5%, 8%, 10%, 15%, 20%, and 23% are prepared. The electron backscatter diffraction analysis reveals that with the increase in the cold-rolling reduction, the proportions of low-angle grain boundary (LAGB) and high-angle grain boundary (HAGB) gradually increase and decrease, respectively. The decrease in HAGB reduces the toughness of the material. With the increase in cold-rolling reduction, the strain area inside the material increases, which enhances the toughness and strength of the steel plate. Austenite textures at different cold-rolling reductions are composed of Brass, Goss, S, and shear texture {011}<122>. The intensity of the Brass-type texture increases with the increasing cold-rolling reduction. The martensite texture mainly consists of R-Cube, Brass, shear texture {111}<110>, {111}<112>, and {332}<113>. When the cold-rolling reduction is less than 15%, the Brass texture appears in the α 0 -martensite phase. In addition, the intensity of the R-Cube texture increases with the increasing cold-rolling reduction. The martensite phase texture is affected by the austenite phase texture, and its formation can be attributed to the Kurdjumov-Sachs orientation relationship.

“…Coryell et al [19] assessed the crystallographic texture as a function of deformation conditions and found that duplex slip along {111} planes contributed to the establishment of the <110> fiber compression texture. Besides, it was found that the typical textures observed in high-temperature austenitic phase for AISI 304LN Stainless Steel [18] was Brass component and Cube/rotated Cube components.…”

“…Moreover, the macro or micro texture evolution during the hot deformation has been well studied, especially for alloys without phase transformation, 1 3 such as aluminum alloys, magnesium alloys and the austenitic steel [15][16][17]. Matruprasad et al [18] found that DRX occurring during the hot deformation brought about formation of Goss and Cube component, but made the deformation texture components, such as Brass and S component, spread and be weaken. Coryell et al [19] assessed the crystallographic texture as a function of deformation conditions and found that duplex slip along {111} planes contributed to the establishment of the <110> fiber compression texture.…”

Deformation behaviour of 5CrNiMoV steel was investigated at temperature 830-1230 °C and strain rate 0.001-10 s −1 . The flow curves were analyzed to illuminate the deformation characteristics. Comprehensive austenite microstructural investigation was carried out using optical microscope for deformed samples. It was found that discontinuous dynamic recrystallization mechanism played a leading part in the nucleation of dynamic recrystallization (DRX) nuclei and growth of DRX grains, and that the austenite grain size increased with deformation temperature, while a larger strain rate was conducive to grain refinement for the quickly generated strain storage-energy favorable for higher DRX nucleation rate. The parent austenite texture evolution and typical martensitic transformation texture for some deformed samples were characterized using electron backscattering diffraction technique and the software of the reconstruction of parent austenite. It was found that increasing temperature contributed to the increase of its maximum of random distribution (MRD) and the strength of rotated Cube texture component, which was probably for the behavior DRX and growth of DRX grains during the hot deformation. The rotated Cube was weakened with the strain rate rising, while the main texture component did not change significantly, which was due to the increase in number of active slip systems and grain fragmentation. Besides, the martensitic transformation texture was related to the parent texture for the variant selection.
