“…To alleviate this stored energy, dislocation cells are generated through the mechanisms of sliding and climbing rearrangement, triggered once the dislocation plug reaches a critical accumulation threshold. During the solution treatment, a sequence of continuous dynamic recrystallization events unfolds in proximity to low-angle grain boundaries, characterized by dislocations [42][43][44][45]. With a progressive augmentation in cold rolling magnitude, the plastic deformation grains within the two austenitic stainless steels, post solution treatment, demonstrably amplify, thereby diminishing the proportions of recrystallized grains and subcrystalline constituents.…”

In this current investigation, the impact of Nickel (Ni) on the microstructural attributes and properties of a cold-rolled 316L sheet was examined. The microstructure and phase configuration of austenitic stainless steels, specifically 316L and 316LNi, were meticulously characterized through the utilization of metallography, X-ray Diffraction (XRD), and Electron Backscatter Diffraction (EBSD) techniques. Subsequent assessments were conducted to evaluate magnetic characteristics, microhardness, and tensile properties. The phase structure of both austenitic stainless steels conforms to a Face-Centered Cubic (FCC) crystal lattice, whereby the grain content oriented along the (110) plane progressively escalates with augmenting degrees of cold rolling. The magnetic conductivity of these austenitic stainless steels satisfactorily adheres to established standards. The incorporation of Nickel (Ni) into the alloy composition enhances the cold deformation capacity of 316L stainless steel. However, substantial plastic deformation yields heightened dislocation density, thereby promoting enlarged grain dimensions upon solution treatment. Throughout subsequent cold rolling deformation sequences, the augmented grain size observed in 316LNi stainless steel leads to a reduction in dislocation density within the equivalently ordered cold-rolled plate. Simultaneously, this augmented grain size engenders a decline in grain boundary content coupled with an augmentation in twin content. Consequently, the interplay of grain coarsening, diminished dislocation density, and twin-induced softening collectively bestows upon 316LNi stainless steel a lower tensile strength compared to 316L stainless steel, albeit accompanied by heightened plasticity.

The deep drawing process in metallic materials has several limitations, such as a stamped depth, the occurrence of wrinkles, the fracture of the sheet before total deformation and the generations of solids with variations in wall thickness. Considering these variables, this work studies the formability of AISI 441 stainless steel under different initial conditions, namely, as-received and rolled to investigate the effect of these variables on the formability of this ferritic stainless steel. The mechanical characterization of AISI 441 steel involved tensile, shearing and Vickers microhardness tests followed by cold stamping, using a deep stamping die. The structural investigation was accomplished by optical microscopy and electron backscatter diffraction techniques. The mechanical behaviour after the stamping process was analyzed by shearing tests on the bottom and wall of the cup and correlated to the deformation limit of the material, and the respective texture characteristics. The shearing test results indicated the effect of the initial condition on the mechanical behaviour after the stamping of AISI 441 steel, which exhibited hardening of the wall and softening at the bottom of the cups. Change in misorientation grain and strengthening of γ-fiber texture component for the rolled condition of AISI 441 steel.

“…The formation of a strong γ-fiber is noted to be beneficial for the formability of FSSs [112]. The significance of a two-step CR process and final annealing to enhance the ridging resistance of high-purity FSS was employed by Gao et al [139,140]. Furthermore, Liu et al [141] reported differences in microstructure and texture evolution in HR and CR FSS.…”

Dislocation slips, twinning, shear banding (SBs), strain localization, and martensite formation are a few deformation modes that are activated in BCC metals and alloys. Strain, strain rate, and deformation temperature are other parameters that determine the activation of deformation modes in BCC alloys. This review focuses on several BCC alloys, such as beta-titanium (β-Ti), tantalum (Ta), and ferritic stainless steels (FSSs), all of which exhibit differences in deformation behavior. These alloys often undergo thermo-mechanical processing (TMP) to enhance their mechanical properties. TMP leads to the evolution of deformation-induced products, such as SBs, strain-induced martensite (SIM), strain localizations, and mechanical/deformation twins (DTs) during plastic deformation, while also influencing crystallographic texture. The deformation modes in β-Ti depend upon the stability of the β-phase (i.e., β-stabilizers); low-stability alloys show the formation of SIM along with slips and twins, whereas in highly stable β-Ti alloys, only slip+twin modes are observed as the primary deformation mechanisms. In the case of Ta, slip activity predominantly occurs on {110} planes, but it can also occur on planes with the highest resolved shear stress. The breakdown of Schmid’s law or non-Schmid behavior for Ta and Ta-W alloys has been discussed in detail. The cold rolling (CR) of FSSs results in the formation of ridges, which is an undesirable phenomenon leading to very low formability. The microstructures of the rolled sheets consist of elongated ferrite grains with in-grain SBs, which are preferentially formed in the γ-fiber-oriented grains. The formation of finer grains after recrystallization improves both the mechanical properties and ridging resistance in FSS. Therefore, this review comprehensively reports on the impact of TMP on the microstructural and crystallographic texture evolution during the plastic deformation and annealing treatment of β-Ti, Ta alloys, and FSSs in BCC materials, using results obtained from electron microscopy and X-ray diffraction.
