Summary: Recent studies have shown that the addition of boron as an alloying element can significantly enhance the wear resistance of different stainless steel grades, but at the expense of corrosion resistance. Designing the chemical composition of the alloys' matrixes is crucial for obtaining corrosion resistant boron-modified stainless steels.

Summary: This study investigated the effects of adding 0.6 wt% B on the microstructures, mechanical properties, and corrosion resistances of PM stainless steels. The results showed that the addition of B significantly improved the sintered densities and corrosion resistances, as well as increased the hardness of the stainless steels. Porosity was found to be a predominant factor influencing the corrosion resistances.

Summary: Localized plastic deformation has been found to make nuclear reactor components more susceptible to stress corrosion cracking (SCC). By analyzing the surface reactivity and corrosion behavior of deformed stainless steel specimens, research has shown that regions with higher dislocation concentrations exhibit increased reactivity due to a reduction in corrosion activation energy. The combination of surface reactivity and strain distributions suggests that SCC cracking is likely to occur in areas with localized strain where micro-galvanic corrosion is favored.

Summary: Additive manufacturing technology offers significant advantages in tailored design of structural components, with sub-micro cellular structures having substantial effects on engineering properties. By focusing on AM austenitic stainless steel as a model material, research has explored the formation mechanisms, kinetics, growth orientation, and stability of these cellular structures. The correlation between cellular microstructure and mechanical properties, as well as corrosion responses, is a key area of concern for advancing high-performance structural alloy development in additive manufacturing.

Summary: The present study investigated the isothermal and cyclic oxidation behavior of 1.4742 ferritic and 310S austenitic stainless steels and their dissimilar metal welds in the air with 30 ± 3% humidity. It was found that the formation of a dense and thin Cr-Fe-Al spinel layer on the surface of 1.4742 stainless steel provided excellent oxidation resistance. However, in cyclic conditions, extensive spallation and mass loss were observed due to the thermal expansion mismatch between different materials. Additionally, ERNiCr-3 weld showed better oxidation resistance by reducing the thermal expansion mismatch and having superior oxidation resistance.

Summary: This paper presents induction-excited shearography as an optical, nondestructive testing method for quick inspection of inner defects and corrosion in austenitic stainless steels. The results show that defects with a size of over 2 mm can be detected at a depth of 1.5 mm using the signal-to-noise ratio (SNR). This technique is suitable for the nondestructive testing of austenitic stainless steels.

Summary: This experimental study examined the effects of dissimilar welding of 316L austenitic and 430 ferritic stainless steels using gas tungsten arc welding process with and without fillers. The results showed differences in microstructural characteristics, mechanical properties, and corrosion resistance between filler welds and autogenous welds. Higher levels of sensitization and pitting were observed in autogenous welds compared to filler welds.

Summary: Structural materials, such as T91 steel and 316 stainless steel, play a critical role in the construction of lead-cooled fast reactors. However, the environmental compatibility of these materials with liquid lead-bismuth eutectic (LBE) needs to be carefully evaluated due to corrosion and structural safety concerns. The addition of silicon in microalloyed steels and stainless steels, such as 9Cr-Si, 12Cr-Si, and ASS-Si, improves their corrosion resistance and microstructural stability, making them promising candidates for lead-cooled fast reactors.

Summary: Friction surfacing is a solid-state deposition process that offers improved microstructural and mechanical properties compared to fusion-based deposition methods. The study investigates the microstructure and corrosion properties of friction-surfaced 304L stainless steel consumable rods on 304L stainless steel substrates. The results show that friction surfacing produces a fine-grained microstructure with distributed strain-induced martensite and high residual compressive stresses, which can mitigate pitting corrosion and potentially chloride-induced stress corrosion cracking (CISCC).

Summary: Austenitic stainless steels are widely used for their excellent mechanical and corrosive properties, with 316L ASS known for its great weldability due to low carbon content. Selective dissolution is a significant issue, primarily caused by the significant difference in electrochemical potential between different phases leading to severe austenite corrosion.

Summary: In this study, the effects of heating temperature and heat soak time on the post-fire stress-strain behaviour of three ferritic stainless steel grades were experimentally investigated. The results showed that the heating temperature and duration had different effects on the three grades. Additionally, two stress-strain models were proposed to capture the post-fire response of these materials.
