Summary: A novel method using nano Bi powder and shift-speed ball milling (SSBM) flake powder metallurgy was proposed for preparing lead-free Cu nano Bi (CNB) alloy materials. The mechanical and tribological properties of the alloy materials were improved by extruding and shearing spherical CuSn10 powder into flakes and evenly dispersing and coating nano Bi powder on the flakes. The mechanical alloying and cold welding processes achieved better combination of CuSn10 matrix in the CNB material, resulting in improved antifriction and wear resistance.

Summary: This study investigated the influence of La2O3-Y2O3 co-doped ZrO2 on its phase transformation behavior, phase stability, and microstructure. It was found that replacing part of Y2O3 with La2O3 increases the tetragonal and cubic phase of zirconia powder, enhancing the fracture strength of the subsequent synthesized materials. Additionally, the stability of zirconia stabilized with La2O3 doping is significantly improved compared to that of Y2O3 alone. The optimal doping amount was found to be 2.8Y0.2La, which exhibited the best phase composition, stability, particle size distribution, and dispersion degree.

Summary: This study investigated the mechanical properties of magnesium phosphate cement (MPC) enhanced by adding fiber and nano-Al2O3, showing improvements in workability and mechanical properties. Increasing fiber content decreased workability while increasing compressive and tensile strength. The addition of micro-steel fiber had the most significant effect on improving flexural toughness. Empirical formulae for predicting strength properties of the fiber and nano-Al2O3 reinforced MPC composite were proposed. The modification mechanisms of nano-Al2O3 on the MPC were revealed through microscopic phase tests.

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.
