“…Abreu et al [42] also pointed out that the low-frequency time constant should be associated with the passive lm on AISI 316 and 304 SS, as the CPE parameter (Q) in high-frequency remained almost constant with the decreasing of lm thickness by prolonging the immersion time (otherwise it could be increased as lm thickness decreased). In our previous work, the low-frequency time constant was also attributed to the passive lm of the Cr-13 type MSS that had been tempered at 500°C for 2-24 h, of which the EIS Bode plot exhibited the same feature as the X818-LC coating in the current work [40] . Therefore, based on the tting results of the current work, the low-and high-frequency time constant of X818-LC sample are attributed to the passive lm and the charge transfer reaction on steel substrate/solution dl, respectively.…”

“…In our previous work, the low-frequency time constant was also attributed to the passive film of the Cr-13 type MSS that had been tempered at 500 °C for 2-24 h, of which the EIS Bode plot exhibited the same feature as the X818-LC coating in the current work. 36 Therefore, based on the fitting results of the current work, the low-and medium-frequency time constant of X818-LC sample are attributed to the passive film and the charge transfer reaction on steel substrate/ solution dl, respectively. Hence, the electrochemical elements displayed in Fig.…”

“…19,[28][29][30][31] Meanwhile, this indication of the time constant in high-or low-frequency range for the electrochemical impedance behavior of passive film and matrix/solution dl has been interpreted differently based on other works. [32][33][34][35][36] Joiret et al 37 studied the electrochemical behavior of oxide film formed on iron in alkaline medium and ascribed the time constant in low frequency range to the passive film, since the real surface area with the roughness introduced by oxide layer should be very large. Abreu et al 38 also pointed out that the low-frequency time constant should be associated with the passive film on AISI 316 and 304 SS, as the capacitance in high-frequency remained almost constant with the decreasing of film thickness by prolonging the immersion time (otherwise it could be increased as film thickness decreased).…”

“…It has been widely reported that the high-frequency time constant should be attributed to the passive lm on SS surface, and the time constant within low-frequency range could be caused by the charge transfer reaction between the steel matrices and solution double layer (dl) [19,[32][33][34][35] . Meanwhile, this indication of the time constant in high-or low-frequency range for the electrochemical impedance behavior of passive lm and matrix/solution dl has been interpreted differently based on other works [36][37][38][39][40] .

Recently, laser cladding (LC) technology has become a cost-effective and convenient method to protect metal substrate from corrosion by producing metal coating with high corrosion resistance. In order to fully investigate the pitting mechanism for high-carbon martensitic stainless steel (HMSS) coating, the microstructure and pitting performance of HMSS samples produced via LC and hot isostatic pressing were comparatively investigated via electrochemical measurements and electron microscopies. Dendritic and network connected M23C6 carbides are the main precipitates in the HMSS coating, while the M23C6 carbides in HMSS bulk are spherical or elongated in shape. Pitting resistance of the HMSS coating is dramatically deteriorated. The massive and continuously distributed dendritic M23C6 carbides could form a large-area cathode and cause the micro-galvanic corrosion of the HMSS-LC coating matrix, thus can be considered as underlying factor for the “loss of passivation” effect of the HMSS coating.

High‐manganese austenitic steels are one kind of superior materials applied in automotive lightweight industry because of their high strength and large plasticity. Herein, transmission electron microscopy and electron channeling contrast imaging combined with electron backscatter diffraction, etc. are used to analyze the microstructural evolution and dominant deformation mechanisms of a Fe–13.6Mn–1.2Al–0.6C (wt%) steel during tensile deformation. Due to the multiple‐stage strain hardening effect, this alloy exhibits excellent combination of strength and plasticity. The yield strength, ultimate tensile strength, and elongation reach 540 (±30) MPa, 1120 (±70) MPa, and 74 (±3)%, respectively. The early hardening stage is fully determined by dislocation accumulation and planar slip. With the strain increasing, the plastic deformation of the steel is dominated by twinning and microbanding, which lead to the synergetic effect of twinning‐induced plasticity and microband‐induced plasticity.

316L austenitic stainless steel (ASS) with a heterogeneous structure exhibits favorable mechanical properties at room temperature, promising excellent application potential. However, the thermal stability of 316L ASS with heterogeneous lamella structure (HLS) has not been adequately addressed yet. Herein, an HLS of 316L ASS is fabricated through 78% cold rolling followed by annealing at 750 °C for 13 min. The detailed investigation focuses on the influence of microstructure evolution on the mechanical properties and corrosion resistance of the alloy after aging at temperatures ranging from 350 to 550 °C for 100 h. The results show that a notable quantity of residual martensite persists even after annealing at high temperatures for a brief duration. The dislocation density of the test steel is reduced after long‐term aging treatment, and the residual martensite is further reversed into austenite during aging. In addition, the aging treatment also promotes further growth of nanocrystalline/ultrafine‐grained, which weakens the heterogeneous characteristics of HLS 316L ASS, resulting in a slight decrease in mechanical properties. However, the decrease in defect density and the enhancement of recrystallization degree are beneficial for eliminating most of the corrosion‐sensitive areas in the cold‐deformed structure, thereby improving the corrosion resistance.
