“…During the deformation process, lattice distortion occurred and the grains were stretched, slipped, and thinned, resulting in substructures, inhomogeneous deformation, and residual stress [23][24][25]. With increasing dislocation density and dislocation interaction, the corrosion activity was enhanced, leading to poor corrosion resistance.…”

Abstract:The corrosion behavior of expandable tubular materials was investigated in simulated downhole formation water environments using a series of electrochemical techniques. The corrosion morphologies in the real downhole environment after three months of application were also observed by stereology microscopy and scanning electron microscopy (SEM). The results show that, compared with the unexpanded sample, the area of ferrite increases dramatically after a 7.09% expansion. The expanded material shows a higher corrosion current in the polarization curve and a lower corrosion resistance in the electrochemical impedance spectroscopy (EIS) plot at every studied temperature. The determined critical pitting temperatures (CPT) before and after expansion are 87.5°C and 79.2°C, respectively. SEM observations demonstrate stress corrosion cracks, and CO 2 corrosion and H 2 S corrosion also occur in the downhole environment. Due to additional defects generated during the plastic deformation, the corrosion performance of the expanded tubing deteriorates.

“…Unlike a regular casing, a SET must undergo radial plastic deformation in the well bore before formal service. Many researchers have shown that the microstructure, dislocation density, texture and residual stress of AISI 304 SS undergo remarkable changes after plastic deformation, resulting in a decrease in the corrosion resistance [4,5]. It is well-known that the dislocation density and texture change during plastic deformation, microstructural transformation occurs because of the low stacking fault energy (SFE) of AISI 304 SS and then straininduced martensite is formed in an austenite matrix [6,7].…”

Related research has shown that the corrosion rate of AISI 304 SS after plastic deformation is proportional to the straininduced martensite content because martensite has higher electrochemical activity than austenite [4,5,8,9]. Besides the martensite content, other factors can also influence the corrosion behavior of AISI 304 SS after plastic deformation.…”

The effects of expansion deformation on the mechanical properties and corrosion resistance of an AISI 304 stainless steel (SS) tube with dimensions of ϕ 108 mm × 6 mm were studied with a full-scale test, a mechanical property test, microstructural analysis and a corrosion property test in order to explore the feasibility of using AISI 304 SS tubes as solid expandable tubes in repairing damaged well casings. The results showed that the AISI 304 SS tube had good expansion performance, suitable strength after expansion and excellent corrosion resistance, and it met the technical requirements for repairing the casings of common oil wells. After ~11% radial expansion, the internal pressure strength and collapsing strength of the tube were 71 and 32 MPa, respectively. The increase in dislocations, and in the formation of strain-induced martensite and twinning stimulated by plastic deformation, led to the yield strength of the AISI 304 SS tube increasing from 249 to 539 MPa; however, the corrosion resistance of the AISI 304 SS tube was somewhat worsened because of the increase in dislocations and strain-induced martensite caused by expansion deformation. However, the corrosion resistance of the AISI 304 SS tube was still much better than that of conventional casings.

“…where The interest on studies about the susceptibility of ASSs to martensitic transformation is due to the great influence of this transformation on mechanical, chemical, and physical properties of these steels. For instance, the formation of DIM was found to decrease the corrosion resistance of ASSs [35,36]. On the other hand, Jha et al [8] studied the failure of an AISI 321 ASS pipeline in a qualification test, where a crack occurred in the bent portion of the cold worked pipe.…”

Austenitic stainless steels (ASS) are corrosion resistant alloys in which the desirable mechanical properties may be attained by cold working in the final stages of the fabrication process. This manufacturing process may induce martensitic transformation from the austenitic phase, where the chemical composition plays an important role as it influences the stacking fault energy (SFE). Therefore, this work evaluated the influence of carbon content on martensitic transformation of Ti stabilized ASS. Thus, the austenite transformed into martensite by cold rolling was observed by Light Optical Microscopy (LOM) and quantified by Vibrating Sample Magnetometer (VSM), and X-Ray Diffraction (XRD) for Ti stabilized ASS with different carbon contents. The experimental results about the martensitic transformation behavior for each alloy were compared with previous results on other ASS and Duplex Stainless Steel (DSS), tested in similar conditions, verifying a high correlation with a sigmoidal model previously applied in these alloys. Additionally, it was carried out a SFE analysis, estimated by thermodynamic model, corroborating that the alloy's carbon content has a strong influence on the material's stability. Finally, it was observed a sudden increase in microhardness value as a consequence of the high amount of austenite transformed into martensite at very low strains that might affect the steels performance in several applications.
