Summary: This study investigated the effect of austenite and ferrite phases on the mechanical properties and corrosion resistance of duplex stainless steel weld metals by substituting Ni with Mn, N, and Mn+N. The results showed that maintaining a 50:50 ratio of austenite and ferrite without harmful phases is crucial for performance, while excessive Mn can decrease corrosion resistance. Additionally, replacing Ni with Mn or N can lead to harder austenite, affecting the overall mechanical properties of the weld metal.

Summary: Poor machining characteristics of super duplex stainless steels (SDSS) lead to tensile residual stress which results in stress corrosion cracking (SCC) under hostile chloride conditions, impacting the service life. This study focused on the effects of machined surface integrity on the SCC of SDSS, finding that different immersion times led to new forms of cracks and localized corrosion. The presence of high density crack formation and transition pit/crack behavior in the microstructure analysis indicated the vulnerability of the ferrite phase to SCC.

Summary: Exposure of duplex stainless steels to high temperatures can cause microstructure changes and precipitated phase formation, leading to significant effects on material properties. In this study, the effects of aging at temperatures ranging from 450 to 850°C on the microstructure and properties of ASTM A890 3A duplex stainless steel were investigated. Different precipitated phases were observed at different aging temperatures, and aging at 450°C increased the strength but decreased impact toughness and corrosion resistance of the duplex stainless steel.

Summary: A self-designed welding flux was successfully used for underwater wet welding of a 5 mm thick 0Cr25Ni6Mo3N duplex stainless steel in 6 mm simulated seawater. The microstructure of the weld centre, heat-affected zone, and base metal were examined, and the microstructural evolution mechanism and phase transition process of the fusion zone were analyzed. The tensile strength of the specimens reached 95.3% of the base metal's tensile strength, with an average elongation of 35.5%. The fracture microstructure showed a mixed fracture type with cleavage steps and a small number of tendons. The Vickers microhardness test results indicated average values of 297.7 HV for the weld center and 278.0 HV for the heat-affected zone. Electrochemical tests revealed that the weld had better corrosion resistance but weaker passivation ability compared to the base metal.

Summary: Keyhole plasma arc welding (PAW) is used to join super duplex stainless steel (SDSS) and achieves full-penetration joints of medium-thickness plates in a single pass. However, the key-holing processes in PAW result in different thermal cycles and microstructures, with substantial differences in the content of austenite and the presence of oxide inclusions. The microstructure in the heat-affected zone (HAZ) is complex, with ferrite and diverse forms of austenite, including grain boundary austenite, intragrain austenite, and Widmansta euro tten austenites. Corrosion resistance is significantly affected by the presence of secondary austenite and chromium nitride in the HAZ.

Summary: The goal of this study is to identify a chemical composition that shows enhanced corrosion resistance and tensile strength compared to AISI 316L without requiring a post-process heat treatment like the conventional duplex stainless steels. Through thermodynamic simulations, it was found that adding 30 wt.-% of AISI 318LN to AISI 316L leads to an austenite/ferrite microstructure in the as-built condition. The strength and corrosion resistance of this new alloy is superior to that of pure AISI 316L, while the ductility is lower.

Summary: In this paper, the initiation of crevice corrosion of hydrogen-charged 2507 was studied and the effect of different Na2MoO4 concentrations on crevice corrosion was investigated. It was found that Na2MoO4 inhibits the adverse effect of hydrogen and enhances the inhibition of crevice corrosion. In addition, hydrogen-charged 2507 crevice corrosion initiates in the austenite phase. While Na2MoO4 improves the crevice corrosion resistance of both phases, crevice corrosion initiation sites changed in reverse, initiating in the ferrite phase.

Summary: This study reveals the effect of nickel addition on the deformation mechanism and hardness evolution in a high entropy alloy during high-pressure torsion processing. The addition of nickel leads to a transition in the plasticity mechanism and an increase in the free energy of phase transformation, resulting in enhanced nano-structuring. The nickel-added alloy shows higher dislocation density and greater extent of nano-structuring, leading to better hardening ability during high-pressure torsion.

Summary: A critical review of the relationship between interlamellar spacing and yield strength of pearlite reveals the contribution of solid solution strengthening of ferrite. By understanding the evolution of solute content and exploring various local equilibria modes, an alloy composition and cooling process have been designed to achieve nano-pearlitic microstructure. Characterization of elemental partitioning and mechanical property assessment show that reduction in ferrite width and increase in post transformation enrichment of pearlite lead to an increase in yield strength in the designed alloy.

Summary: The effect of aging treatment on the strength-ductility combination of intercritically annealed medium Mn steel was studied. The results showed that both one-stage and two-stage aging treatments significantly improved the strength-ductility product of the steel. One-stage aging resulted in the formation of nano-sized NiAl precipitates, while two-stage aging led to phase-selective precipitation of varying sizes of NiAl. The two-stage aged sample exhibited a combination of TRIP-TWIP effect and precipitation strengthening, leading to sustained three-stage work-hardening during deformation and improved strength-ductility combination.

Summary: In the current market scenario, high quality requirements are needed for cold-rolled steel sheets in order to suit the continuous automated forming process for various end applications. The deep drawability, an important property for steel in forming applications, is influenced by factors including alloy chemistry, microstructure, texture evolution, and precipitation characteristics. The present study investigates the influence of boron to nitrogen (B/N) ratio on the mechanical and drawing properties of low carbon, low manganese, and low sulfur steel using a specially designed continuous annealing process. The results show that a B/N ratio of 0.185 leads to the best combination of properties, with low yield strength to ultimate tensile strength ratio, high plastic anisotropy, and desirable yield strength, ultimate tensile strength, uniform elongation, and total elongation values. It is found that the B/N ratio, rather than the absolute boron content, plays a significant role in the precipitation characteristics of carbides and the development of favorable texture during the continuous annealing process.

Summary: The study examined how the composition of welding electrodes affects the mechanical and corrosion integrity of welded AISI 2205 duplex stainless steel in a chloride environment. Two types of electrode coatings, basic and acidic, were developed and their thermal stability was confirmed through thermogravimetric analysis. Various standards were employed to evaluate the chemical composition, mechanical properties, microstructure, and corrosion characteristics of the welded joints. The ultimate tensile strength and Vickers hardness of the welded joints were influenced by the basicity index of the electrode coating, and the amperage used during welding impacted the resistance to corrosion in the chloride environment.
