Summary: In this study, a high-strength and heat-resistant Al-Ce-Sc-Zr alloy was designed and fabricated by additive manufacturing. The as-built alloy exhibits excellent strength and ductility, with an ultimate tensile strength of 445 MPa, a yield strength of 344 MPa, and an elongation of 10%. Even at 300 degrees C, the alloy still maintains a superior tensile yield strength of 233 MPa, surpassing other high-temperature aluminum alloys reported previously. The outstanding performance is mainly attributed to the formation of fine, homogeneous, and coarsening-resistant Al11Ce3 intermetallic nanoparticles during the rapid solidification process, as well as the presence of coherent Al3(Sc, Zr) nano-precipitates and interfacial segregation at the interface of intermetallic nanoparticles during high temperature exposure.

Summary: This study investigates the thermal properties of a high-strength Al-Mg-Sc-Zr alloy fabricated by SLM. The alloy exhibits low thermal conductivity in the as-built condition, which improves after aging. Abnormal non-linear thermal dilatation behavior is observed at high temperatures. The study also finds an orientation dependency in both thermal conductivity and dilatation, which is associated with grain alignment and melt pool structures.

Summary: In this study, dynamic stretching behaviors of Al-Mg-Mn-Sc-Zr alloy at various strain rates were investigated, revealing that with increasing strain rates, the alloy exhibited significant increases in peak stress and elongation, as well as improved work hardening ability. The increase in dislocation density and decrease in dislocation width enhanced resistance to dislocation movement, leading to a notable increase in peak strength. High velocity dislocations could cut through Al-3(Sc,Zr) particles, inhibiting dislocation tangle formation and promoting uniformity in dislocation distribution, ultimately improving the plasticity of the alloy during dynamic deformation.

Summary: In this study, the Al-Mn-Mg-Sc-Zr alloys were 3D printed using laser powder bed fusion and subjected to different heat treatments. The heat treated alloys showed an increase in strength but a decrease in ductility. The secondary precipitates of Al6Mn and Al3Sc played a positive role in the strengthening of the alloy.

Summary: Thermal-resistant Al-Zr based conductor alloys were developed by microalloying with a low level of Sc (<= 0.10 wt%) and two thermomechanical processing routes. The alloys exhibited high strength and excellent electrical conductivity due to the precipitation of fine Al-3(Sc,Zr) precipitates. The Sc-containing alloys also showed outstanding thermal-resistant properties with minimal strength reduction after thermal exposures.

Summary: In this study, the anisotropy of the Al-Zn-Mg-Sc-Zr alloy sheet in the peak-aged state was analyzed, showing that grain orientation and Schmid factor significantly affect the alloy properties. Samples at 0 degrees and 90 degrees have higher strength but lower elongation due to wider distribution of Schmid factors, while samples at 45 degrees and 60 degrees have lower strength but higher elongation due to narrower distribution of Schmid factors.

Summary: The research shows that the Al-Mg-Mn-Sc-Zr alloy softens significantly at high temperatures due to a decrease in dislocation density, changes in grain boundaries, and the thermal activation promoting dislocation movements and grain boundary softening. Additionally, the dispersed nano-sized Al3(Sc,Zr) particles formed by adding trace amounts of Sc and Zr have strong inhibition effects, but their effectiveness weakens at higher temperatures, leading to a substantial reduction in flow stress.

Summary: The study investigated the effects of different Zr/Sc ratios on the microstructural evolution and mechanical properties of Al-2Si alloy. It was found that a Zr/Sc ratio of 1:1 led to refinement of alpha-Al phases and modification of eutectic Si structure, resulting in a significant improvement in ultimate tensile strength and elongation. Additionally, the fracture model of the alloy changed to ductile fracture at 250 degrees C.

Summary: Selective laser melting (SLM) of Sc and Zr modified Al-Mn alloy was studied systematically, focusing on density behavior, microstructure, and mechanical properties. Process parameters significantly affected relative density, with up to 99.8% achieved at optimized parameters. High energy density resulted in spherical pores, while low energy density led to irregular pores in SLM-processed Al-Mn-Sc-Zr. The material exhibited duplex grain microstructure and good mechanical properties, with no significant anisotropy between horizontal and vertical directions.

Summary: Accelerated coarsening was observed in the extruded melt-spun ribbon with larger precipitate size and higher precipitate volume fraction than in melt-spun ribbon. The accelerated effective diffusivity after extrusion was explicitly linked to the initially refined extruded microstructure. Predictions using the Umantsev-Olson-Kuehman-Voorhees model for ternary alloys showed good agreement with experimental results by considering changes in diffusivity and precipitate volume fraction.

Summary: The study systematically investigated the effects of process parameters and aging treatment on the microstructure and mechanical properties of a high Mg-content Al-Mg-Sc-Zr aluminum alloy fabricated using selective laser melting. Increased Mg content in the alloy helped reduce texture, while laser scanning speed significantly influenced the Vickers hardness of the samples. After aging treatment, the mechanical properties were further improved, with enhanced microhardness and compressive yield strength compared to known Al-Mg-Sc-Zr alloy fabricated using SLM.

Summary: The study generated cell atlases of human intervertebral discs (IVDs) in both neonatal and adult stages and analyzed their composition, distribution, and function. Comparison of the cell atlases revealed the existence of different cell populations and their developmental trajectories. The findings provide insights into the cellular biology of IVDs and may have implications for the development of novel therapeutic targets for IVD degeneration.
