Summary: A stable SUS316LN austenitic stainless steel was cold-rolled to 92% reduction to form a complicated heterogeneous nanostructure. The material showed high tensile strength along the transverse direction, and peak aging further increased the strength. Grain-boundary segregation and the nano-lamellar structure contributed to the high strengthening effect.

Summary: Understanding the solute interaction effects on grain boundary segregation, precipitation, and fracture of Fe-Ni-Ti-(Mo) maraging steels is crucial for the development of improved steel performance. The addition of Mo effectively suppresses intergranular embrittlement by reducing the segregation of Ni and Ti, inhibiting the formation of coarse Ni3Ti precipitates and precipitate-free zones at grain boundaries, and enhancing grain boundary cohesion.

Summary: This study investigates the migration behavior of a faceted Sigma 11 boundary in Cu doped with Ag atoms, revealing that solute atoms segregate to a facet with more free volume and greatly reduce boundary velocity in one migration direction. However, a directionally-dependent motion mechanism can escape solute pinning and speed up migration in the other direction, uncovering a new mechanism of chemically-induced anisotropy in grain boundary mobility.

Summary: In this study, the segregation characteristics of Mo and other alloying elements at grain boundaries in super-austenitic stainless steels were investigated through calculations and experiments. The influence of B and Ce on the segregation was analyzed, and the microscopic mechanism of precipitation in steels containing B and B + Ce was discussed. The results showed that the micro-alloying of B and B + Ce could inhibit the segregation of Mo at grain boundaries, leading to discontinuous and finer precipitates.

Summary: First-principles calculations were conducted to investigate the Sigma 5(310) grain boundary in Fe with B, C, and P, revealing the embrittlement caused by P and the de-embrittling effect of B and C. The energetic preference of interstitial B and C over interstitial P was found, with only substitutional P exacerbating grain boundary cohesion. The study demonstrated that the influence of these elements on the grain boundary cohesion is a complex interplay between mechanical and chemical contributions.

Summary: Achieving strength and toughness synergy through microstructure design is challenging in materials science. In this study, the authors develop a bamboo-like dual-phase copper-boron structure that simultaneously increases hardness, strength, and ductility. By using grain boundary engineering, the composition and bonding structure of neighboring crystallites can be tuned to strengthen materials, especially those composed of small nanograins. The findings suggest that constructing dual-phase nanocomposites with metal nanograins embedded in a strong and confining light-element grain boundary framework can be a new avenue for strengthening metals.

Summary: The aim of this review is to summarize recent achievements in the development of ultrafine-grained austenitic/ferritic stainless steels through large strain deformation. The paper discusses various methods of large strain deformation for producing ultrafine-grained metallic materials. It also explores the structural mechanisms responsible for grain refinement during plastic deformation and examines the physical and mechanical properties of ultrafine-grained stainless steels. The review concludes that the development of ultrafine-grained microstructures during severe plastic deformation is a result of continuous dynamic recrystallization, with the misorientations among strain-induced cells/subgrains progressively increasing.

Summary: Unique nanorod precipitates with a core-shell structure are found to nucleate from the grain boundaries of a bulk nanocrystalline Al-Ni-Y alloy. The local structure and chemistry of these features during annealing are studied. As annealing time increases, more nanorods transform to an ordered structure while the shell chemistry transitions from Y-rich to Ni-rich. The correlation between the nanorods and amorphous complexions is observed.

Summary: This study aims to reveal the atomic-scale effects of tempering on the complex substructures and stress corrosion cracking resistance of high-strength martensitic steels. The surprising finding is that tempering leads to a decrease in SCC resistance, contrary to the known effect. Analysis of subboundaries in the martensitic microstructure shows that carbon segregation at the lath boundaries during tempering acts as a precursor to harmful cementite, ultimately degrading the SCC resistance of the material.

Summary: The effect of adding a trace amount of 0.1 wt% (0.02 at%) tin on the structure and phase composition of an Al-Si-Cu alloy was studied. The results showed that the tin-containing alloy exhibited significantly higher hardness and achieved peak hardness in a shorter aging time compared to the tin-free alloy. Finer precipitates of the theta' phase and tin nanoparticles were observed in the tin-containing alloy. Compression tests revealed that the yield strength of the tin-containing alloy was substantially higher than that of the tin-free alloy, indicating its potential as a material for new-generation engine parts.

Summary: Characterizing the nanostructure of modern oxide dispersion strengthened steels requires a comprehensive analysis using complementary techniques. This study applied small-angle X-ray scattering, transmission electron microscopy, and atom probe tomography to several oxide dispersion strengthened steels, and compared the results to determine the inclusion types and their density. The presence of oxide inclusions and nanosized clusters enriched with O, Y, V, Ti, Al, and Zr were observed, depending on the steel composition. The accurate determination of inclusion types is crucial for hardness calculations, and the calculated values were confirmed by microhardness measurements.

Summary: The influence of decreased temperature of tensile testing on annealing-induced hardening (AIH) and deformation-induced softening (DIS) effects in an ultrafine-grained (UFG) Al-Zr alloy was studied. The UFG Al-Zr alloy exhibited a DIS effect accompanied by an increase in the elongation to failure delta. Both the AIH and DIS effects weakened at lower tensile test temperatures. The activation energy Q of plastic flow was estimated for the alloy in various states and showed changes with annealing and additional straining.

Summary: Superplastic deformation of polycrystalline materials is usually achieved by diffusion-assisted grain boundary sliding at high temperatures. Recent research has shown that room-temperature superplasticity can be achieved in ultrafine-grained Al-Zn based alloys, but the underlying mechanism is still unclear. This study utilized in-situ tensile straining, electron microscopy characterization, and atomistic density functional theory simulation to reveal that the superplasticity at room temperature is achieved by grain boundary sliding and grain rotation, facilitated by the continuous diffusion of Zn. The diffusion of Zn atoms from grains to grain boundaries forms a Zn nanolayer, acting as a solid lubricant to lower the energy barrier of grain boundary sliding.

Summary: This paper investigates the changes in microstructure and properties of an Al-Fe alloy produced with different solidification rates, severe plastic deformation, and rolling. The results show that the as-cast alloy obtained with a graphite mold predominantly consists of Al6Fe phase particles, while the alloy produced with an electromagnetic mold has a mixture of Al2Fe phase particles. Two-stage processing using equal-channel angular pressing and cold rolling leads to the development of ultrafine-grained structures, achieving high tensile strength and electrical conductivity in both alloys. Further cold rolling results in a smaller grain size and refinement of second phase particles, maintaining high strength after annealing. The combination of mechanical strength, electrical conductivity, and thermal stability make these Al-Fe alloys a potential conductor material compared to existing commercial systems like Al-Mg-Si and Al-Zr, depending on engineering cost and efficiency in industrial production.

Summary: Fatigue failure of crystalline materials is a challenging problem in science and engineering. Recent research has shown that fatigue crack growth can occur in intermittent jumps with fat-tailed distributions. In this study, we combined macroscale crack tip tracking with postmortem scanning electron microscopy imaging to study fatigue crack growth in aluminum 5005 samples. We found a similar distribution of striation spacings as jump sizes, indicating the occurrence of avalanchelike crack propagation. Our findings suggest that fracture surfaces can provide insights into the intermittency of fatigue crack propagation and the development of crack-resistant materials. The advantages and disadvantages of the two introduced methods are discussed.

Summary: In this study, the mechanical properties of high-Mn steel subjected to equal-channel angular pressing (ECAP) were investigated at cryogenic temperatures. The results showed that ECAP led to grain refinement and the formation of nanotwins, resulting in a heterogeneous hierarchical structure. This microstructure greatly enhanced the strength of the steel in a cryogenic environment. The effects of heterogeneity induced by heavy straining of the initially coarse-grained material were also discussed.
