Ce addition enhances the microbially induced corrosion resistance of Cu-bearing 2205 duplex stainless steel in presence of sulfate reducing bacteria

Lu Yin et al.

Summary: The addition of cerium over 0.18 wt.% effectively inhibits the formation of SRB biofilm on the surface of 2205-Cu-Ce DSS, significantly reducing corrosion tendency, indicating that exceeding a critical value of cerium addition can enhance the antibacterial effect of Cu-bearing 2205 DSS against SRB-induced corrosion.

Numerical analysis of the deformation behavior of 2205 duplex stainless steel TIG weld joint based on the microstructure and micro-mechanical properties

Song Gao et al.

Summary: The study utilizes a microstructure-based finite element model to analyze the microscale strain and macroscopic deformation response in different regions of the 2205 duplex stainless steel weld joint. By examining the microscopic strain distributions, it is found that the location and quantity of strain localization bands are mainly determined by the microstructure morphology.

Characterization of inhomogeneous microstructure and mechanical property in an ultra-thick duplex stainless steel welding joint

Yu Wan et al.

Summary: The study found that the variation of austenite content and grain boundary character distribution in welding affects the mechanical properties of the welding joint, leading to a decrease in mechanical strength and an increase in elongation along the thickness direction; in the transverse direction, the weld metal has the highest strength, followed by the heat-affected zone and base metal, while the trend of elongation is opposite to that of strength.

Effects of low-temperature neutron irradiation on the microstructure and tensile properties of duplex 2304 stainless steel and its electron-beam welds

Chinthaka M. Silva et al.

Summary: The study investigated the microstructural and mechanical properties of a lean duplex stainless steel material (2304-grade) under irradiation conditions, showing radiation hardening and decreased total elongation. Fracture surfaces of irradiated samples exhibited nonuniform quasi-cleavage and shearing, indicative of radiation-induced embrittlement. Furthermore, elemental segregation was identified in the post-irradiated base metal.

Hydrogen Stress Cracking Behaviour in Dissimilar Welded Joints of Duplex Stainless Steel and Carbon Steel

Hanji Park et al.

Summary: This study investigates the effect of weld microstructure on hydrogen stress cracking behavior in dissimilar gas-tungsten arc welds of DSS and carbon steel. It found that certain weld microstructures, harmless under normal conditions, had a negative impact in a hydrogen atmosphere leading to premature rupture of the weld. Hydrogen-enhanced strain-induced void (HESIV) and hydrogen-enhanced localised plasticity (HELP) mechanisms were identified as causing premature fracture in these welds.

Synergistic Strengthening Effect of Reinforcing Spark Plasma Sintered Al-Zn-TiC Nanocomposites with TiC Nanoparticles

Hany S. Abdo et al.

Summary: Al-10Zn-TiC nanocomposite powders were prepared by mechanical alloying with varying reinforcement content, and bulk samples with 10 wt% TiC reinforcement showed a grain size of 17 +/- 08 μm and improved load carrying ability. Microscopic analysis confirmed the presence and distribution of reinforced nanoparticles in the Al matrix, with XRD results showing TiC formation, SEM analysis revealing uniform distribution of particles, and TEM showing clear interface between matrix and TiC nanoparticles. Mechanical properties testing indicated higher strength in nanocomposites due to multiple strengthening mechanisms from nanoscale TiC addition.
