Microstructural influence on the electrochemical corrosion behaviour of dual-phase steels in 3.5% NaCl solution

Mechanical Properties and Corrosion Behaviors in 3.5% NaCl Solution of Grade-A and Dual-Phase Steels Welded by FCAW

“…It is concluded that the higher and the lower intercritical annealing temperatures are influenced on the martensite morphology and distribution of the phase constituents. Similar observations were also reported in the related literatures (Sarkar, 2005 andBhagavathi, 2011).…”

“…It has been reported (Sarkar, 2005) that island-like morphology of martensite gave better corrosion resistance as compared to the network form surrounding the ferrite grains. In present study, martensite phase has similar island-like morphology in the matrix of ferrite in dual phase steel developed following intercritical annealing at higher temperature of 800 o C. The microstructure of dual-phase steel coded 730DP developed following intercritical annealing at lower temperature of 730 °C is composed of uniform fibrous ferrite and martensite, which is commonly termed as a fibrous structure.…”

“…Nowadays, it was reported the corrosion performance of dualphase steel embedded in concrete by Ismail et al (Ismail, 2009) and Keleştemur et al (Keleştemur, 2009), the mechanical properties and corrosion susceptibility of dual-phase steel in concrete by Trejo et al (Trejo, 1994), microstructural influence on the electrochemical corrosion behaviour steels in 3.5% NaCl solution by Sarkar et al (Sarkar, 2005) and mechanical and corrosion behaviours of plain low carbon dual-phase steels by Bhagavathi et al (Bhagavathi, 2011). It was no any report the corrosion behaviours in 3.5% NaCl solution of the transformed dualphase steels welded by FCAW.…”

Corrosion-Resistant High-Entropy Alloys: A Review

“…Figure 4 shows the comparison of E pit , the parameter which can represent the resistance to pitting corrosion, and i corr , which is relevant to the corrosion rate as indicated in Equation (1), obtained through polarization tests in the 3.5 wt % NaCl solution at room temperature. The results were compared with those of some conventional alloys, including stainless steels, Al alloys, Ti alloys, Cu alloys, and Ni alloys [60][61][62][63][64][65][66]. The HEAs are located in the lower right part of the figure.…”

Preliminary Investigation of the Corrosion Behavior of Proprietary Micro-alloyed Steels in Aerated and Deaerated Brine Solutions

“…The adherence and protectiveness of the corrosion product film is related to the presence of these cementite platelets which strengthen and anchor the films to the metal substrate (Ref 42,45). Some authors (Ref 32,41,42,61) have also reported that cementite acts as cathode, while the ferrite acts as the anode in ferritepearlite microstructures. It follows that the specimen with higher cathode-anode (pearlite-ferrite) ratio should be more susceptible to corrosion attack (Ref 23,24,60).…”
