Summary: In this study, the effect of B addition on the microstructures and properties of Cu-15Ni-8Sn alloy in different states was investigated. The presence of Ni6.67SnB2 phase was observed in the as-cast microstructure, and B addition could alleviate the segregation of Sn at the grain boundary. Solution treatment did not eliminate the Ni6.67SnB2 phase, leading to significant influences during aging. Increasing B content inhibited the transformation of DO22 phase into L12 phase and suppressed discontinuous precipitation. Appropriate B addition maintained peak hardness during aging, indicating enhanced softening resistance. These findings provide guidance for the design of high-performance Cu-Ni-Sn alloys.

Summary: Designing a metastable microstructure with coherent nano-sized precipitations in the matrix is an effective approach to improve materials' strength. In this study, the evolution of nano-sized Cu-rich clusters in an AM-processed Fe-15Cu-15Ni alloy was investigated. The results indicate that the laser-based AM process induced phase decomposition and led to the formation of nano-sized Cu-rich clusters, which contributed to the increase in average cluster size and hardness of the alloy. Adjusting the processing parameters can optimize the mechanical properties of materials by enabling nano-sized cluster and phase formation.

Summary: This paper investigates the preparation of Cu-15Ni-8Sn alloys using additive manufacturing techniques, specifically laser powder bed fusion (L-PBF) and laser-directed energy deposition (L-DED), followed by solutionizing, cold rolling, and aging treatment. The results show that this unconventional process significantly improves the yield strength and elongation of the samples, while also reducing the preparation time. The microstructural and mechanical changes of the samples subjected to the same pre-deformation aging treatment are consistent, indicating a similar strengthening mechanism for the two printed samples.

Summary: This study systematically investigated the evolution behavior of the gamma-D0(3) phase in Cu-15Ni-8Sn alloy, revealing the direct formation of particulate gamma-D0(3) phase and the precipitation of lamellar and needlelike phases. After the solid-solution treatment, the gamma-D0(3) phase would re-nucleate at the grain boundary and grow during aging, forming discontinuous precipitation colonies. The addition of B effectively suppressed the formation of gamma-D0(3) phase, resulting in improved hardness and reduced electrical conductivity of the alloy.

Summary: The effects of solidification rate on the microstructures and mechanical properties of the directionally solidified Cu-15Ni-8Sn alloy were investigated. It was found that the solidification rate has a significant influence on the phase distribution and morphology of the alloy. Higher solidification rates result in reduced dendritic spacing, smaller primary phase size, and more uniform distribution. The alloy's segregation problem was greatly improved. Homogenization treatment further enhanced the uniformity of the alloy's composition and microhardness distribution, while reducing the time required for the treatment.

Summary: The newly designed Fe-Cr-based medium-entropy stainless alloy exhibits high ageing hardness, compressive stress, and corrosion resistance compared to conventional precipitation hardening stainless steel. The transformation of the well-dispersed B2-ordered phase to a D0(3) crystal structure after ageing at 500 degrees Celsius results in a significant ageing hardening effect.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
