Summary: In this study, a cyclic oil quenching process was used to treat the common medium-carbon steel #45 steel, resulting in the formation of fine-grained structure. This structure exhibited a superior tensile strength of over 1690 MPa and moderate ductility. The refined grains and imbedded dislocations were found to be crucial in enhancing the strength. Furthermore, the material showed increased strength and ductility under dynamic tension due to the strain rate effect.

Summary: In this study, stress-induced martensitic transformation (SIMT) has been effectively demonstrated to achieve a significant cold reduction of -43% and -45% in the metastable Ti-10V-2Fe-3Al and Ti-5Al-5V-5Mo-3Cr alloys, respectively. The presence of stress-induced alpha '' martensites provides preferential nucleation sites for new strain-free grains formation upon recrystallization annealing. Thermomechanical treatment results in a grain refinement of -93% and -80% for Ti-1023 and Ti-5553 alloys, respectively. The diffusivities of alloying elements, such as Fe, Mo, V, Cr, and Al, have been confirmed to alter the stability of the fl phase during recrystallization annealing, as evidenced by Electron Probe Micro Analyzer (EPMA). The effect of grain size on the SIMT ability based on microhardness variations has also been deduced.

Summary: A processing route involving cryorolling and annealing was used to achieve heterogeneous grain structures in a Cr15Fe55Mn20Ni10 ferrous medium-entropy alloy. Through phase reversion and partial recrystallization, cryorolled sheets exhibited a heterogeneous microstructure with multi-scale grains, resulting in higher yield strength and fracture elongation compared to room-temperature rolled sheets. The improved mechanical properties were attributed to grain boundary hardening, hetero-deformation-induced hardening, and dislocation hardening.

Summary: The chemical ordering and its effect on structure and elastic properties of Mg1-xScx alloys are studied using the ab initio method. The MgSc alloys exhibit a strong tendency for chemical long-range ordering as the Sc concentration increases. The presence of chemical long-range ordering leads to a lattice distortion and the formation of a low symmetric orthorhombic martensitic phase in MgSc alloys, indicating a chemical-structural coupling. The chemical long-range ordering also significantly increases the elastic moduli of the alloys.

Summary: The effects of different crystallographic orientations of the grains on damping capacity (tan8) in magnesium alloys were investigated. The results showed that the grain orientation had a significant impact on the damping capacity of pure magnesium and Mg-Sc alloy.

Summary: The study investigated the structural and functional properties of Fe-Mn-Al-Ni shape memory alloy sheets produced using hot rolling. The as-processed condition showed a high fraction of the non-transforming g-phase, resulting in good workability but poor superelasticity. The alloy had good structural properties with a high yield strength of 600 MPa. Solution annealing resulted in a microstructure with no preferred orientation and larger grains. Thermo-mechanical processing had no impact on the subsequent texture but provided enough driving force for abnormal grain growth. Cyclic heat treatment achieved oligocrystalline structures with grain sizes above 10 mm, exhibiting superelastic properties similar to laboratory-processed material.

Summary: This paper mainly introduces the relationship between thermodynamics, kinetics, thermo-kinetic partition, nucleation, and growth. It discusses the scale of thermo-kinetic correlation and its relation to the stability of phase transformations and plastic deformations. By integrating nucleation and growth, separating them, and designing negative driving forces, the principle of high thermodynamic driving force-high generalized stability is reinterpreted. Therefore, this work is helpful for designing nucleation and growth to achieve high strength and high plasticity.

The effects of the coating on oxidation resistance, electrical charging, and flowability were investigated. The results showed that the chromium coating reduced oxidation and improved the flowability of the powder.

Summary: This study demonstrates that the high-temperature alpha-Al2O3 phase can still be formed even if microdischarge is fully suppressed under specific processing conditions. Through the use of various techniques, the microstructural and chemical evolutions accompanying the gamma to alpha alumina transition were studied. The results provide strong evidence that the alpha phase can form spontaneously in regions of oxide with the appropriate temperature, grain size, and impurity distributions.

Summary: This study develops a computational method for efficiently generating realistic 3D aggregates using micro X-ray Computed Tomography (μXCT) images, spherical harmonic (SH) analysis, and a random-field reconstruction algorithm. The method decomposes the real aggregate surface segmented from CT images, maps it with the SH function to radius fields at different scales, and reconstructs new aggregates based on statistical data and a folding algorithm. The method is verified by comparing morphology indices and demonstrated its flexibility in reconstructing new sets of random aggregates with specified morphology indices.

Summary: Recent studies have shown that achieving an atomically flat surface for metals can greatly improve their oxidation resistance and enhance their electronic-optical applications. Researchers have explored the use of graphene as a covering layer to achieve atomically flat surfaces. They found that high-temperature deposited graphene on copper surfaces formed mono-atomic steps, while annealed copper and transferred graphene on copper interfaces formed multi-atomic steps.

Summary: Elemental powders of Al, Ti, Sc, and Zr are blended and processed via laser powder-bed fusion to create binary and ternary alloys. The microstructural analysis and mechanical testing show that the addition of Ti results in the formation of primary precipitates, while the addition of Sc and Zr leads to the formation of fine grain bands. The Al-0.25Ti-0.25Zr alloy exhibits comparable strain rates to Al-0.5Zr at low stresses, but significantly higher strain rates at higher stresses during compressive creep testing. Finite element modeling suggests that the connectivity of coarse and fine grain regions is a critical factor affecting the creep resistance of the alloys.

Summary: The limited slip systems of magnesium (Mg) and its alloys hinder their wide applications. By conducting tensile straining experiments, researchers discovered a rate-dependent transition in the dislocation mechanisms of Mg alloys. At high strain rates, glissile dislocations dominate, while easy-glide dislocations dominate at low strain rates. Abundant glissile dislocations do not necessarily improve ductility.

Summary: Inverse temperature dependences of the detwinning stress were observed in face-centered cubic deformation twins in Cu-8at.%Al alloy. The detwinning stress increased with temperature when the pi detwinning mode was involved, but decreased when the pi/3 mode was involved. The dual effect of temperature on the detwinning stress was due to the reduction of internal stresses pre-existing within the deformation twins. The complete reduction of internal stresses at about 530 degrees C led to the equivalence of the critical stresses of different detwinning modes and a decrease in the yield stress anisotropy of the twin/matrix structure.

Summary: The elastic-plastic transition in magnesium alloy Mg-4.5Zn exhibits bursts of deformation, which are characterized by sudden changes in grain orientation. These bursts occur in a coordinated manner among nearby grains, with the highest burst rate observed at the onset of full plasticity. The most significant burst events are associated with twinning, supported by the observation of twinned structures using electron microscopy. The bursts are often preceded and followed by a stasis in peak movement, indicating a certain "birth size" for twins upon formation and subsequent growth at a later stage.

Summary: A novel testing system for miniature specimens is designed to characterize the plastic response of materials for which conventional full-size specimens cannot be extracted. The system has an automated operation process, which reduces the damage to specimens caused by manual handling and improves the stability of the test results. The experiments show that the miniature specimens extracted from stainless steel and aluminum have high reproducibility, and the results are consistent with those of conventional-sized specimens. A correction procedure is provided to consider the influence of surface roughness and heat-affected zone caused by wire EDM.
