Abstract Sigma phase is a deleterious phase which can be formed in duplex stainless steels (DSSs) during heat treatment, manufacturing, or welding processes, leading to a decrease of mechanical properties and corrosion resistance. This issue is highly concerning for numerous industries because the presence of σ–phase in the austenite/ferrite microstructure of DSSs reduces their lifetime and promotes a brittle fracture in service. This review focuses on the non-destructive techniques (NDT) for th...

This research evaluates the behavior corrosion of galvanized steel (GS) and AISI 1018 carbon steel (CS) embedded in conventional concrete (CC) made with 100% CPC 30R and two binary sustainable concretes (BSC1 and BSC2) made with sugar cane bagasse ash (SCBA) and silica fume (SF), respectively, after 300 days of exposure to 3.5 wt.% MgSO4 solution as aggressive medium. Electrochemical techniques were applied to monitor corrosion potential (E corr) according to ASTM C-876-15 and linear polarizatio...

Twinning-induced plasticity (TWIP) steels have higher strength and ductility than conventional steels. Deformation mechanisms producing twins that prevent gliding and stacking of dislocations cause a higher ductility than that of steel grades with the same strength. TWIP steels are considered to be within the new generation of advanced high-strength steels (AHSS). However, some aspects, such as the corrosion resistance and performance in service of TWIP steel materials, need more research. Appli...

The protection of mild steel by modified epoxy coating containing colophony microencapsulated corrosion inhibitors was investigated in this study. The corrosion behavior of these epoxy coatings containing colophony microcapsules was studied by electrochemical analysis using cyclic potentiodynamic polarization and electrochemical impedance spectroscopy. The microcapsule coating showed decreased corrosion current densities of 2.75 × 10−8 and 3.21 × 10−8 A/cm2 along with corrosion potential values ...

The corrosion behavior of austenitic Fe-Mn-Al-Cr-C twinning-induced plasticity (TWIP) and microband-induced plasticity (MBIP) steels with different alloying elements ranging from 22.6-30 wt.% Mn, 5.2-8.5 wt.% Al, 3.1-5.1 wt.% Cr, to 0.68-1.0 wt.% C was studied in 3.5 wt.% NaCl (pH 7) and 10 wt.% NaOH (pH 14) solutions. The results obtained using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques, alongside optical microscopy analysis, revealed pitting as the...

The corrosion behavior of the sulphuric-anodized AA2099 using two different current densities, 0.19 or 1.0 A·cm−2, with two different sealing treatments in H2O and 6 wt.% Na2Cr2O7 at 95 °C was studied in 3.5 wt.% NaCl and 10 vol.% H2SO4 solutions. The AA2099 is widely used in aeronautical applications, thus it is essential to present good corrosion performance in chloride and acid rain environments. The surface morphology of the anodized film was characterized by scanning electron microscopy (SE...

Abstract This work analyzes the premature corrosion failure of a welded AISI 304 stainless steel (SS) pipe network in well water (WW) for 6 months. Laboratory tests were performed to analyze the corrosion behavior and to identify and distinguish the genera of bacteria. Pipe specimens were analyzed using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, open circuit potential, cyclic potentiodynamic polarization, and electrochemical impedance spectroscopy.
