“…These multiplex effects decrease the grain size of the microstructure after transformation and improve the strength and toughness of the steel [ 25 ]. It also compensates for the loss of strength arising from the lower carbon content of the ULCB steel.…”

“…Moreover, the change in niobium content causes a change in the chemical composition, which significantly affects the phase transition behavior and the corresponding microstructure. The composition and microstructure play an important role for determining the corrosion susceptibility of steel [ 25 , 26 , 27 ]. However, the effect of niobium content on the seawater corrosion resistance of ULCB steel is still unclear.…”

Four types of ultra-low carbon bainite (ULCB) steels were obtained using unified production methods to investigate solely the effect of niobium content on the performance of ULCB steels. Tensile testing, low-temperature impact toughness testing, corrosion weight-loss method, polarization curves, electrochemical impedance spectroscopy (EIS), and the corresponding organizational observations were realized. The results indicate that the microstructure of the four steels comprise granular bainite and quite a few martensite/austenite (M/A) elements. The niobium content affects bainite morphology and the size, quantity, and distribution of M/A elements. The elongation, yield strength, and tensile strength of the four types of ULCB steels are above 20%, 500 MPa, and 650 MPa, respectively. The impact toughness of the four types of ULCB steels at −40 °C is lower than 10 J. Steel with Nb content of 0.0692% has better comprehensive property, and maximum charge transfer resistance in 3.5 wt.% NaCl solution at the initial corrosion stage. The corrosion products on the surface of steel with higher niobium content are much smoother and denser than those steel with lower niobium content after 240 h of corrosion. The degree of corrosion decreases gradually with the increase of niobium content at the later stage of corrosion.

“…Katiyar et al have evaluated the corrosion resistance of five different microstructures for high carbon steel in 3.5 pct NaCl solution. [69] If the phases are arranged in the order of reduction in corrosion resistance, the order becomes pearlite, bainite, spheroidized carbide, martensite, and tempered martensite. Thus, the ferrite + pearlite structure of the base metal revealed better resistance against corrosion than the WN.…”

In the present investigation, friction stir welding (FSW) was carried out on C-Mn steel using various welding parameters. The microstructural examination of the weld nugget (WN) region revealed different area fractions of cementite, pearlite, bainite, and martensite within the ferrite matrix. The average hardness in the region of the WN was higher than the base material. The corrosion behavior of the WN and base metal was investigated. The base metal underwent uniform corrosion. Localized pitting corrosion was dominant in the region of the WN. The primary corrosion products were c-Fe 2 O 3 (maghemite), c-FeOOH (lepidocrocite), and Fe 3 O 4 (magnetite). The corrosion rate of the WN was significantly higher than that of the base metal. However, the same was considerably lower than the conventionally fusion-welded specimens. Further, the corrosion rate of the WN increased with the increment in the rotational speed of the tool. The change in the corrosion rate at the WN for various specimens was influenced by the matrix grain size, quantity of second phase, area fraction of special boundary, and relative quantity of low-and high-angle grain boundaries.

“…DP steels comprising of delicate ferrite and hard martensite show better mechanical properties looked at than regular HSLA steels (Abedini et al 2019;Song et al 2020). That has driven the specialists to investigate their appropriateness for various structural and constructional purposes (Katiyar et al 2019). Though plenty of research articles were published concerning a generally excellent blend of mechanical properties in DP steels (Karimi et al 2017;Basantia et al 2021;Bilal et al 2019;Fereiduni and Ghasemi Banadkouki 2014;Kumar et al 2019;Shahzad et al 2018;Xiong et al 2019;Zhao et al 2019;Zhu 2019), further examinations are important to discover the impact of phase constituents on the corrosion resistance properties (Bignozzi et al 2020;Gürkan Aydın 2019;Ma et al 2020;Prabhu et al 2020a, b;Zhang et al 2020).…”

This paper presents the corrosion and inhibition behavior of heat-treated EN8 dual-phase steel with ferrite-martensite structure with pectin in 0.5 M sulphuric acid. The corrosion studies were performed using the weight loss method, electrochemical techniques such as potentiodynamic polarization measurements, and impedance spectroscopy. The study was done at different concentrations of pectin in the temperature range of 40 to 70 °C and immersion time of 1, 3, 5, and 7 h. The results showed that the inhibition performance of pectin has enhanced with an increase in pectin concentration and decreased with the temperature and time of exposure. From the weight loss study, highest inhibition efficiency of 76.43% was achieved at 5.0 g/L at 1 h of exposure at 40 °C. The maximum inhibition efficiency of 62% was obtained with 5.0 g/L of pectin at 40 °C by potentiodynamic polarization method. The energy, enthalpy, and entropy of activation and also thermodynamic parameters like free energy, enthalpy, and entropy of adsorption were assessed and discussed. Appropriate adsorption isotherm was fit to the obtained experimental outcomes and achieved Langmuir adsorption isotherm to be the best fit and obeyed physical adsorption. Surface analysis: scanning electron microscopy, X-ray diffraction techniques, atomic force microscopy, and energy dispersive X-ray were done with and without the addition of pectin. The metal surface appears to be uniform and smooth in the presence of pectin and adsorption was confirmed by surface analysis.
