Summary: By applying pre-strain warm surface mechanical attrition treatment, the bending fatigue life of NiTi plates has been improved. The treatment resulted in the formation of amorphous and grain size gradient layers, as well as the generation of compressive residual stress on the surface of the plates. These characteristics provide higher resistance to fatigue crack nucleation and growth, significantly enhancing the fatigue life of the plates.

Summary: The morphologies and compositions of internal oxides on Ti60 alloy after corrosion under solid NaCl in H2O+O2 at 600 & DEG;C have been studied by TEM. The microstructure has an effect on the internal corrosion process. The partial pressure of Cl2 was found to be higher inside the & beta; strip and at the & beta; phase/& alpha; platelet boundary, which promotes the corrosion process in & alpha;s grains located inside the & beta; strip. Our results confirm that the internal oxides do not originate from the oxidation of chlorides. Titanium depletion caused by the Cl attack promotes oxidation of the matrix.

Summary: In this study, the thermodynamic mechanism and general behavior of spinodal decomposition in high-entropy alloys (HEAs) were investigated. Contrary to the high mixing entropy theory, it was found that increasing the number of elements could increase the possibility of spinodal decomposition. The effects of temperature, entropy, and enthalpy were also clarified, and the high entropy effect on pseudo-binary decomposition was proposed. These findings provide a necessary paradigm for understanding and utilizing spinodal decomposition in HEAs.

Summary: A 3-axis room-temperature impact with intermediate annealing treatment can significantly increase the strength of bulk 316L stainless steel without causing fracturing. The impacts from multiple directions result in the smallest nanograins and a high volume of thin twins, while inhibiting the formation of martensite phase. The annealing treatment induces element segregation and recovers the capability of the steel in storing dislocations, leading to excellent ductility and low hardness anisotropy.

Summary: The additive manufacturing of Ni-based superalloys has attracted significant attention for its ability to fabricate complex components for high-end industrial systems. However, the rapid heating and cooling processes can induce high levels of residual stress and lead to severe metallurgical defects. Understanding the mechanisms of residual stress and crack formation is crucial to prevent cracking and enable wider application of these materials. This paper reviews the residual stress and crack formation mechanisms in additively manufactured Ni-based superalloys and presents methods for inhibiting crack formation.

Summary: In this study, nanotwinned structures with extremely fine twin boundary spacing were synthesized, and their mechanical responses were systematically investigated under different loading directions. Continuous strengthening was observed in columnar-grained nanotwinned Ni and Ni alloys, contrary to the softening effect observed in nanotwinned metals with equiaxed grains. The mechanism for continuous strengthening was found to transform from twin boundary obstructing dislocations to dislocation starvation-dominated mechanism as the twin boundary spacing decreased to a critical value.

Summary: Researchers have found a way to create narrow-gap metal oxides by carefully controlling the hydrolysis reaction of metal alkoxides. This allows for the carbothermal reaction to occur at temperate conditions in open air. The introduction of oxygen vacancies through partial hydrolysis drives the color transformation of the oxides and enhances photothermal conversion efficiency. This method opens up new possibilities for the development of black metal oxides with tailored charge transition behavior for solar photothermal applications.

Summary: The study reveals the surface-initiated rolling contact fatigue (RCF) failure mechanism under heavy load and initial high roughness surface. The results indicate that precursor of collapsed morphology and nanocrystalline layer are the main factors causing lower RCF life with high roughness compared to low roughness surfaces. The spalling failure initiating from low roughness surface under heavy load is strongly dependent on surface plastic deformation.

Summary: This study investigates the competitive relationship between fretting fatigue and plain fatigue in press-fitted railway axles. By changing the depth of the stress relief groove, the plain fatigue limit and fretting fatigue strength were tested. Detailed information was gathered, and an evaluation methodology integrating finite element simulation and the Modified Wohler Curve Method was established. The study concludes that the optimal groove depth, which balances the anti-fatigue capabilities, depends on the number of test cycles.
