Summary: The NC-304 austenitic stainless steel with low Si content shows superior high-temperature oxidation resistance compared to steels with excessive Si addition. The unique nanocrystalline microstructure and distribution feature of Si in NC-304 accelerate the formation of a continuous SiO2 healing layer, effectively reducing the oxidation rate at least up to 1000 degrees C.

Summary: A novel cast multi-phase stainless steel (CMPSS) with ferrite, martensite, and austenite was prepared. The solid solution and tempering treatment resulted in high strength and toughness, with the precipitation of nanoscale Laves phase causing dislocation pinning in ferrite. However, prolonged tempering time or increased tempering temperature led to coarse precipitation of Laves phase along the phase boundary, damaging the strength and toughness. High-temperature tempering also reduced the retained austenite content and promoted the precipitation of the R phase in ferrite, negatively affecting the mechanical properties of CMPSS.

Summary: The tensile properties of nanocrystalline 304 stainless steel plate (NSSP-304) and its conventional polycrystalline 304 stainless steel (CPSS-304) counterpart were studied. NSSP-304 exhibited higher ductility, larger strengths, and more isotropic deformation compared to CPSS-304. The microstructures of fractured NSSP-304 and CPSS-304 were also analyzed, showing more stable and homogeneous microstructures in NSSP-304.

Summary: 304 stainless steel powder, cast WC powder, and 304 close-grained stainless steel wire mesh were used to prepare cast WC particle-reinforced 304 stainless steel composites. The effects of cast WC mass fraction, sintering temperature, and rolling deformation on the properties of the composites were investigated. The results show that the hardness and yield strength of the composites were positively influenced by all three process parameters. Higher temperature or cast WC content led to clustering of cast WC particles, resulting in brittle fracture and reduced tensile strength and plasticity of the composites. Increasing rolling deformation helped improve the strength and plasticity of the composites. The optimum content of cast WC in the blended powder was found to be 10 wt.%; the perfect sintering temperature was 1200 degrees C, and the best rolling reduction was 35%.

Summary: Spatially gradient microstructures have been found to enhance the strength-ductility synergy of austenitic stainless steels. In this study, a new approach called plate surface mechanical rolling treatment was used to produce a bulk gradient nanostructure in a 304 stainless steel plate. The resulting sample showed ultra-high yield strength and considerable uniform elongation in tensile tests. Analysis revealed that the mechanical incompatibilities and dislocation activities contributed to the outstanding strength-ductility synergy in the gradient nanostructured stainless steel.

Summary: The effect of hydrogen on the phase transformation, deformation twins, and dislocation density of metastable stainless steel 304 was investigated. Hydrogen charging resulted in the formation of a large amount of alpha-martensite, a high density of deformation twins, and an increased dislocation density compared to the uncharged state. This caused a significant loss of ductility by 60% in the presence of hydrogen in metastable austenitic stainless steel. Alpha-martensite and twins were preferred sites for crack initiation and propagation, leading to increased susceptibility to hydrogen embrittlement.

Summary: Diffusion bonding was used to join 90 W-7Ni-3Cu alloy with 304 stainless steel using CuZnMnNiSi high-entropy alloy as an interlayer. The study found that a strong joint with mutual diffusion across the interfaces can be achieved at a bonding temperature of 900 degrees C. SEM and HRTEM analysis revealed the preferential diffusion of interlayer elements into the base materials due to their smaller atomic radius and high activity. The joint exhibited excellent tensile strength of 403 MPa and good ductility, with the tensile fracture occurring at the interface of 304SS/interlayer.

The effects of preparation parameters and coating structure on performance were investigated through various microscopy techniques and nano scratch testing. The results showed that the monolayer Ta coating exhibited the lowest friction coefficient and wear rate, attributed to its excellent adhesion, unique structure, and solid lubrication. Moreover, the coatings showed different wear resistance in simulated body fluid (SBF) and atmospheric environments.

Summary: The effects of oxidation temperature on microstructure, phase composition, oxide film thickness, hardness, and element distribution of Zr-2.5Nb alloys were investigated. The results showed that the oxide film thickness and hardness increased with increasing oxidation temperature. The oxide film consisted mainly of ZrO2 and Nb2O5. The content of m-ZrO2 in the oxide film increased gradually with increasing temperature, while the content of Nb2O5 remained unchanged. A suitable thermal oxidation temperature significantly improved the corrosion resistance of the Zr-2.5Nb alloy. The wear resistance of the oxidized specimens was also significantly improved.

Summary: The microstructure, mechanical properties, and corrosion properties of Zr-xCo (x = 0, 2, 4, 6, 8, 10 at.%) binary alloys were systematically studied. Microstructure analysis revealed the presence of Zr3Co phase. The addition of Co improved the strength of the alloy, with the highest ductility observed at 6 at.% Co. Corrosion tests showed that Co addition positively affected the corrosion resistance of the alloy, leading to a denser passivation film and reduced corrosion behavior. Analysis of the passive film composition revealed the presence of ZrO2, Co3O4, Co(OH)2, and Zr2O3.
