Summary: This paper compares the tensile and high cycle fatigue properties of three 439 stainless steels from different suppliers, and evaluates their properties at different temperatures. The results show that although the tensile properties of the steels are similar, their fatigue properties differ, with fatigue strength inversely related to crack resistance. The decline in fatigue strength of ferritic stainless steel is influenced by carbide precipitation, solute atom diffusion, and weakening of the ferrite grain boundary at high temperatures. The fatigue strength can be quantitatively predicted based on the cleavage surface in the fatigue crack source.

Summary: By conducting low cycle fatigue (LCF) tests on SLM 316L and traditional 316L, it has been found that SLM 316L exhibits stable cyclic softening behavior and higher fatigue life compared to traditional 316L. This is attributed to its higher strength as well as the coarsening of cellular sub-structure, evolution of geometrically necessary dislocations (GND), and influence of texture direction.

Summary: This study investigates the dependence of the characteristics of nitrided layers on ferritic stainless steel on their initial microstructures. It was found that ferritic stainless steel with a solid solution and annealing treatment showed the best performance after low-temperature plasma nitriding. The nitrided layer thickness and hardness significantly increased, and the wear and corrosion resistance of the nitrided layer were improved.

Summary: The low-cycle fatigue behavior of Z3CN20.09M austenitic stainless steel was studied in high temperature water and at room temperature in air. It was found that the fatigue life in water was shorter and decreased with decreasing strain rate. Ductile striations were observed at the lowest strain rate, indicating anodic dissolution. The experimental results were consistent with the prediction models.

Summary: The ultra-high power laser-MIG hybrid welding technique is an effective method for joining thick-walled components, but the fatigue properties of the joints are rarely studied. This research aims to uncover the evolution of fatigue behavior in thick weldments along the penetration direction. The derived S-N curves show a decreasing trend in fatigue strength, and the failure location shifts from the heat affected zone to the weld center in the depth direction. The mechanism of fatigue crack initiation and propagation is discussed, revealing that shrinkage cavities in the lower layer decrease fatigue performance. The research results provide theoretical guidance for the use of ultra-high power laser-MIG hybrid welded joints.

Summary: Ferritic nitrocarburizing treatment can enhance the surface hardness of Si-Mo-Al cast iron SiMo1000, but it also significantly decreases its fatigue and oxidation resistance, leading to the formation of microcracks and aluminum depletion, causing decarburization.

Summary: The study investigated the influence of commercial low carbon ferrochromium (LCFeCr) additions on the inclusion characteristics in Ti-containing ferritic stainless steel. It was found that the addition of FeCr alloys led to a decrease in titanium content and the transformation of MnCr2O4 spinel inclusions into Ti2O3-Cr2O3-based liquid and solid inclusions.

Summary: The plasticity of welded 441 ferritic stainless steel joints can be controlled by varying the laser beam spot diameter during laser welding. The results showed that increasing spot diameter led to increased weld melt width and weld column crystal size, but decreased isometric crystals in the center of the weld. Additionally, increasing spot diameter resulted in decreased tensile strength, elongation after breaks, and area reduction.

Summary: The core-shell structure of Ti/Nb precipitates in UNS S44660 was revealed using FIB-TEM. In bromide solution, Nb in the shell preferentially dissolves, leaving micro-crevices. The strong anodic adsorption of Br- and the large strain field in the shell promote the dissolution of residual Mo. Micro-crevices surrounding the Ti-rich nucleus expand into pits, leading to preferential pitting corrosion at Ti/Nb precipitates.

Summary: High-temperature creep-fatigue behavior of Alloy 709 was investigated through strain-controlled tests at 650°C and 750°C, revealing fluctuations in creep-fatigue life at 650°C due to Dynamic Strain Aging. Linear damage summation (LDS) was used to create a creep-fatigue interaction diagram, showing increased crack and creep cavity density at 750°C compared to 650°C.

Summary: This study investigates the evolution of microstructure and mechanical properties of low chromium ferritic stainless steel 410S through accelerated thermal aging. The results show that the increase in aging time leads to the formation of Cr-rich alpha' phase near ferritic grain boundaries and the growth of carbides, which affect the hardness, strength, and plasticity of the material.

Summary: The study investigated the effect of Al content on the high-temperature oxidation behavior of 18Cr-Al-Si FHSS. Results showed that higher Al content reduced oxidation rate, improved oxidation resistance, and promoted the formation of denser and more continuous Al2O3 film in the early oxidation stages.

Summary: The addition of Ce and Zr enhances the wear resistance of nickel-saving austenitic steel by increasing the work-hardening rate and reducing the dynamic recovery and recrystallisation softening effect. Furthermore, Ce- and Zr-containing alloys can form a wear-protective glaze layer to reduce high-temperature wear.

Summary: The microstructure and properties of medium-carbon cast steel alloyed with different amounts of Ni and tempered at different temperatures were investigated. Adding 0.47-1.59 wt.% Ni resulted in the formation of 16%-36% retained austenite (RA). The hardness of the steel was influenced by the precipitation of carbides and the hardness of martensite. Excessive RA content led to intergranular impact rupture and low impact energy, while carbides formed at specific tempering temperatures reduced the impact energy further. Tempering at certain temperatures increased impact energy due to the formation of specific carbides and low-carbon martensite. Steel with high impact energy showed excellent impact-abrasive wear resistance, with micro-cutting and delamination being the primary wear mechanisms.
