Summary: The microstructural evolution and mechanical behavior of Fe-0.2C-2.7Mn-1.2Si-0.8Al-0.3Cr quenching and partitioning steel were investigated. The results showed that the microstructures consisted of tempered lath martensite, bainitic ferrite, retained austenite, and blocky fresh martensite. The fraction of retained austenite decreased with increasing partitioning temperature, while the yield strength was negatively affected by prolonged isothermal holding time.

Summary: The addition of Mn, Yb and Zr has a positive influence on grain size in AlYb and AlMnYbZr alloys. Cold rolling results in a deformed structure of the grains with no changes in their size. The precipitation hardening behavior at different temperature intervals was also observed in both alloys after ageing.

Summary: The influence of cold rolling on thermal and mechanical properties, as well as microstructure observation of cast AlZnMgCu(ScZr) alloys, was investigated, revealing the presence of eutectic phases and various quasicrystalline structures in the materials. The hardening of the alloys was mainly attributed to phase precipitation, with the addition of Sc,Zr stabilizing grains and preventing recrystallization at elevated temperatures.

Summary: The addition of potassium-doping in tungsten sheets has been found to improve mechanical properties, especially with a lower brittle-to-ductile transition temperature in cold-rolled sheets, attributed to finer grain size. This suggests the potential for increased performance in high-temperature environments compared to pure tungsten.

Summary: The fluidity tests of pure aluminum 1070 and Al-Si alloys revealed that the fluidity of 1070 was optimal with a channel gap of 0.8 mm and lower Si contents. Heating the die had a smaller impact on the fluidity of 1070 compared to the Al-Si alloy. As the Si content increased, the fluidity showed different trends.

Summary: The study investigated the combined effect of solution treatment temperature and severely cold rolling on hydrogen partitioning and related fracture mechanism, revealing different trap sites including coarse Al2Cu particles as a relatively strong trap site for hydrogen. It was found that high hydrogen concentration induced by the environment can lead to decohesion and void formation at Al2Cu coarse particles, promoting premature fracture.

Summary: With the increasing demand for portable electronics, electric vehicles, and grid-scale energy storage systems, the development of next-generation rechargeable batteries with high energy density becomes crucial. Pure silicon has shown potential as a high-capacity electroactive material, but its volume changes during charging and discharging processes lead to issues such as fracturing and capacity decay. This Account highlights the progress made in the development of pure silicon anodes and discusses strategies to overcome these challenges.

Summary: The High-Temperature Scanning Indentation (HTSI) method is used to continuously monitor mechanical properties such as Young's modulus, hardness, and creep properties during specific thermal cycles. This study applies the HTSI method to cold-rolled samples of commercially pure aluminum and oxygen-free high conductivity (OFHC) copper. The observed variations in hardness during heating are attributed to static recovery and static recrystallization, and inverse analysis using metallurgical models provides insights into the influence of initial deformation state and heating rate on kinetics parameters. Electron-Back Scattering Diffraction measurements further support the findings, and the study demonstrates the HTSI method's capability to quantify restoration parameters with temperature through well-designed experiments.

Summary: The tensile behavior of cold-rolled 304L stainless steel at room temperature (RT) and liquid nitrogen temperature (LNT) was investigated, revealing that LNT exhibits higher strength and ductility due to the combined effects of high density dislocations, transformation-induced plasticity (TRIP), and delamination toughening mechanism. This study provides insights into the deformation mechanisms and mechanical properties of 92% cold-rolled 304L stainless steel at RT and LNT.

Summary: Grain boundaries (GBs) are crucial for the mechanical behavior of polycrystalline materials, yet the atomic-scale dynamic processes of GB deformation remain unclear. This study presents an in situ atomic-resolution investigation on how sliding-dominant deformation occurs at general tilt GBs in platinum bicrystals, involving direct atomic-scale sliding and sliding with atom transfer across the boundary plane.

Summary: This article reports a finding that single-crystal 2D materials can be epitaxially grown on twinned crystals. By establishing a geometric principle to describe the alignment of 2D materials on high-index surfaces, the authors demonstrate that 2D material islands grown on the two sides of a twin boundary can be well aligned. They also successfully grow wafer-scale single-crystal graphene and hexagonal boron nitride films on the surfaces of twinned copper foils. This discovery greatly increases the availability of large area high-quality 2D single crystals and expands the fundamental understanding of materials epitaxy.

Summary: The microstructure, hardness, and tensile properties of copper processed by high pressure surface rolling (HPSR) were investigated. It was found that HPSR resulted in a gradient structure with significant differences in microstructural features. The deformed microstructure varied from nano- and ultrafine-scale structures near the surface to lightly deformed grains at depths below the surface. Partial recrystallization occurred after annealing, with a more pronounced effect close to the surface. The deformed layer at depths greater than 500 μm remained largely non-recrystallized after annealing.

Summary: This study investigates the anisotropy in mechanical properties of AlSi10Mg alloy fabricated by metal additive manufacturing (AM). The researchers found that the microstructural inhomogeneity is the main factor leading to anisotropic mechanical properties, and post-AM heat treatment can alleviate this anisotropy through homogenization of the microstructure and redistribution of residual stresses. By applying an appropriate heat treatment process, the anisotropy in mechanical properties can be effectively reduced, resulting in a good strength-elongation synergy.

Summary: The high strength of nanocrystalline metals is of great interest, but their low ductility and microstructural instability pose challenges. Previous experimental works have shown that grain boundary segregation of solute atoms can overcome these disadvantages. However, the microscopic mechanisms are not well understood yet. Computational simulation has provided insights into the effects of solute atoms on the structure, energy, and mechanical properties of segregated grain boundaries in nanocrystalline metals.

Summary: This study used a surface sliding friction treatment at liquid nitrogen temperature to create nanostructured surface layers in an Al-Cu-Mg alloy. Characterization of the nanostructured surface was done using 3D orientation mapping and atom probe tomography. The results showed the presence of low angle grain boundaries dominating the nanoscale structure and high angle lamellar grain boundaries exhibiting a preference for the {101} plane. The atom probe tomography analysis revealed segregation of Cu and Mg atoms at the lamellar boundaries, which is believed to contribute to boundary stabilization and structural refinement.
