“…Following cold rolling and subsequent recrystallization processes, a signi cant grain re nement and the dominance of gamma ber texture were observed in our case. This phenomenon has been widely reported in the literature [6,41]. It can be attributed to stress localization during rolling and the stored energy associated with the gamma texture compared to other textures [29,42].…”

Interstitial-free (IF) steel is the purest form of steel and has tremendous scope for a basic understanding of the corrosion behavior of steel. A total of five steel samples were subjected to progressive cold deformation at varying levels (35%, 50%, 65%, 80%, and 95%) and subsequently subjected to uniform heat treatment. After heat treatment, the samples were characterized, revealing an increased volume fraction of gamma fiber texture with higher levels of cold reduction. Polarization tests were performed in acidic (0.5M HCl) and neutral (0.6M NaCl) solutions. The results demonstrated that samples with a higher volume fraction of texture ND//<111 > displayed elevated corrosion current and corrosion rate, suggesting a potential influence of grain boundary characteristics on corrosion behavior. Additional measurements on the depth of attack within the grains and at the grain boundaries further supported the notion that the corrosion behavior of the material is affected by grain boundary properties. These findings contribute to a better understanding of the corrosion mechanisms in IF steel and highlight the significance of grain boundary nature in the context of corrosion behavior.

“…The role of the degree of RRs during CR and subsequent annealing on X2CrNi12 FSS has also been reported, and the evolution of different texture components and their corresponding volume fractions are shown in Figure 11a-f [112]. Figure 11a-c demonstrates the recrystallization of ferrite grains following heat treatment of 50% CR samples.…”

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.

“…Table 3 lists the specific parameters values of the fitting results. The corrosion performance of the specimen was correlated with Rt; the larger the value of Rt, the lower the corrosion rate [34]. The Rt of the cold sprayed TC4 alloy coating and the Mg-Li alloy substrate reached 2.36 × 10 4 and 1.90 × 10 2 Ω•cm 2 , respectively.…”

Mg-Li alloys have achieved vital applications in aerospace, automotive, and 3C fields for their prominent properties. However, the Mg-Li alloy exhibits poor corrosion and wear resistance due to the high activity of Mg and Li elements and low hardness of Mg. Accordingly, TC4 alloy coating was prepared on the surface of Mg-Li alloy using the cold spray technique to enhance the surface properties. Moreover, the microstructure, microhardness, tribological properties, and corrosion resistance of the coating were systematically investigated. As indicated by the results, the interface between the coating and the Mg-Li alloy substrate was mechanical bonding without significant defects. Several pores exist in the cold sprayed TC4 coating for its high elasticity, toughness, and passivation, resulting in a porosity of 4.3%. The microhardness of the cold sprayed TC4 coating reached 296.3 HV, marking a notable increase in comparison with the substrate. The TC4 alloy coating has better wear resistance than the Mg-Li alloy substrate. The wear volume of the cold sprayed TC4 alloy only accounted for 38% of that of Mg-Li alloy. Abrasive wear was the major wear mechanism of the TC4 alloy coating. In electrochemical tests, the corrosion current density of the TC4 alloy coating (1.426 × 10−5 A/cm2) was two orders of magnitude lower than that of the magnesium-lithium alloy substrate (1.008 × 10−3 A/cm2), and the corrosion potential of the TC4 alloy coating was higher, which indicates that the coating has excellent corrosion resistance.
