“…Figure 8 shows the Nyquist plots and the corresponding Bode plots of the 2205 DSS after atomisation tests in the AIM solution. In general, a large diameter capacitive loop suggests a good corrosion resistance of the steel, and the size of the capacitive reactance arc indicates the stability of the passivation film [26 28]. The radius of the capacitive loop in the low-frequency region decreased gradually with increasing duration of atomisation, indicating that the corrosion resistance was reduced as time elapsed.…”

The corrosion behavior of 2205 duplex stainless steel (2205 DSS) was investigated by atomization tests, which was performed in an S-bearing thin electrolyte layer used as the artificial industrial-marine environment. Electrochemical methods and X-ray photoelectron spectroscopy (XPS), were conducted to reveal the protection properties and the composition evolution of the passive film. The results indicated that the corrosion time would weak the protectiveness of passive film, which was attributed to the accumulation of defects and metal sulfides in the passive film. The decrease of composition percentage of Cr 2 O 3 made more negative effects on the protection properties of passive film than the increase of Cr(OH) 3 and CrO 3 , whose formation was related to the adequate supply of oxygen and water molecules. The metal sulfides such as NiS and MoS 2 formed during atomization tests reduced the content of alloy oxides in the passive film, and provided locations for the growth of defects.

“…Previous work is usually done by increasing the degree of plastic deformation to improve the mechanical properties of steel wire, but the method has entered the bottleneck, so there is an urgent need to find new ways or methods to improve mechanical properties. Cheng J et al [2,3] have made great contributions to high strength bridge cable steels, and mainly investigated the effect of N/C ratio on organizations and properties of high-strength weathering steels. Skolyszewski A, Cetlin P R, et al [4,5] studied cold-drawn steel wire, and found that factors such as drawing times, drawing modular angle and compression rate can change the strength of the wire.…”

High-strength cable-steel bridge is the “lifeline” of steel structure bridges, which requires high comprehensive mechanical properties, and cold-drawing is the most important process to produce high-strength cable-steel bridge. Therefore, through the ABAQUS platform, a bridge wire drawing model was established, and the simulation analysis on the process of stress strain law and strain path trends for high-strength bridge steel wire from Φ 12.65 mm by seven cold-drawing to Φ 6.90 mm was conducted. The simulation results show that the wire drawing the heart of the main axial deformation, surface and sub-surface of the main axial and radial deformation occurred, with the increase in the number of drawing the road, the overall deformation of the wire was also more obvious non-uniformity. In the single-pass drawing process, the change in the potential relationship of each layer of material was small, and multiple inflection points appeared in the strain path diagram; the change in the seven-pass potential relationship was more drastic, which can basically be regarded as a simple superposition of multiple single-pass pulls.

“…[1][2][3][4][5] It can also be used as structural steel for railways, vehicles, bridges, and towers and can withstand long-term atmospheric exposure. 6 In the future, an increasing amount of WS will be used in low-temperature environments (below the scope of the usual test temperature of the weather-resistant welding material, i.e., below -5°C). Thus, there is a requirement for appropriate welding consumables in the case of such materials.…”

In this study the Mn content fluctuations in the deposited metals and their influence on the impact toughness and corrosion resistance were investigated. The experimental results indicated that the deposited metal containing 1.05 w/%Mn when compared with the deposited metal containing 1.34 w/%Mn increased the impact toughness by 40 % and that the increment in energy absorbed by the crack propagation accounted for 88 % of the increment in impact energy. Further, the self-corrosion potential difference between the deposited metals and the weathering steel was less than 20 mV, leading to similar corrosion resistances. The results revealed that the Mn content fluctuations did not significantly influence the self-corrosion potential of the deposited metals; furthermore, the increase in the impact toughness can be attributed to: a) the decrease in the volume fraction of the grain-boundary ferrite and ferrite side plates in the columnar zone, b) an increase in the number of large grain boundaries in the fine-grain reheating zone, and c) the refining of the martensite-austenite constituents.
