Summary: The Neumann-Kopp rule for aluminum containing compounds creates a specific heat kink due to the pure aluminum description in the SGTE Unary database. Two approaches were explored to address this issue. The reverse Neumann-Kopp approach was found to be inapplicable due to a systematic overestimation of Cp. Another method of defining the Cp based on composition average and normalized temperature was proposed, resulting in better agreement with experimental data and eliminating the need for defining Cp of aluminum above its melting point.

Summary: In this study, the microstructure evolution and mechanical properties of (Ce + Yb) modified in-situ TiB2/Al-Si matrix composite under different thermal deformation conditions were investigated. It was found that specific thermal deformation parameters resulted in the reduction or elimination of micropores, refinement of certain phases, and more uniform distribution of submicron TiB2 particles. These changes led to improved strength and plasticity of the composite, with the ultimate tensile strength, yield strength, and elongation reaching significantly higher values compared to the as-cast and undeformed composite.

Summary: The microstructure and thermal-physical properties of Al-xNi (x = 6-25 wt.%) alloys were investigated. The volume fraction and size of Al3Ni increased significantly with the increase of Ni content, while the morphology remained unchanged. The thermal expansion coefficient (CTE) and thermal conductivity (TC) both decreased. The CTE of Al-6 wt.%Ni alloy was 20.2 x 10-6/K at 100°C, decreasing to 15.4 x 10-6/K for Al-25 wt.%Ni, indicating favorable thermal expansion performance. The TC ranged from 202.8 W/(m·K) to 103.9 W/(m·K). Additionally, the structure and thermal properties of Al3Ni were studied using first-principles calculation to provide relevant thermodynamic data. The linear CTE of Al3Ni at 100°C was found to be 13.82 x 10-6/K. Based on experimental and computational results, the modified Turner and general Effective Medium Theory (GEMT) models were used to explain the relationship between microstructure and thermal expansion coefficient, thermal conductivity of Al-xNi alloys.

Summary: This study investigates the effect of micro-alloying agents on the solidification and rheological behaviors of Al-5Ni alloy. The results show that the addition of micro-alloying elements can significantly refine the -α Al grains, leading to the improvement of thermal conductivity and mechanical properties. This research provides an in-depth understanding of the correlation between solidification route and rheological behavior of micro-alloyed Al-5Ni melts.

Summary: The effects of 1.0 wt% cerium (Ce) addition on the solidification behavior, microstructure, and mechanical properties of 6063 aluminum alloy were investigated in this study. Cerium addition caused the formation of Al-Ce and iron-free Al-Si-Ce precipitations, leading to a reduction in grain size by 25%. Vickers hardness measurements showed an increase in hardness for both the reference and Ce-modified alloys, but the Ce-modified alloy exhibited lower strengthening due to silicon depletion. Compression test results also revealed lower yield and ultimate strength for the Ce-modified alloy, attributed to silicon depletion impairing the precipitation hardening process.

Summary: This study investigates the effects of Sm/Yb on the microstructure, electrical conductivity, thermal conductivity, and thermal expansion properties of hypereutectic Al-Fe alloys through experiments and first-principles calculations. The results show that the addition of Sm/Yb effectively modifies the primary Al13Fe4 phase, leading to improved electrical conductivity, thermal conductivity, and thermal expansion performance. The modification is attributed to the transformation of the coarse primary intermetallic phase into fine and star-like particles, reducing electron and phonon scattering. Theoretical calculations suggest that the stable adsorption of Sm/Yb on the surface of Al13Fe4 inhibits preferential growth. This study demonstrates the effectiveness of rare earth element modification in controlling primary phase morphology and improving thermal-physical properties.

Summary: This study systematically investigated the effects of ytterbium on the microstructure, electrical/thermal conductivity, and mechanical properties of Al-5Ni alloy. The experimental results showed that the addition of ytterbium could simultaneously improve the yield strength, ultimate tensile strength, and electrical/thermal conductivity. Ytterbium formed Al3Yb phase, which helped decrease the solubility of impurity elements in the alpha-Al matrix.

Summary: This study investigated the factors affecting eutectic Si modification in Al-Si hypoeutectic alloy with the addition of Na, Sr, Eu and Yb, and found that the modification effect is determined by element concentration in eutectic Si, solubility of modifying element M in alpha-Al, and interaction energy parameter of Al (or Si) and modifying element. A good modification is achieved by M of limited solubility in alpha-Al and a moderate interaction energy parameter of Si (or Al) and M. The results were verified by previous experimental results, and the effect of cooling rate on modification was also discussed.

Summary: The addition of microalloying elements Sc and Zr in eutectic Al-6Ni alloy can create additional precipitates, resulting in substantial precipitation strengthening. The strength of the alloy at ambient and elevated temperatures can be quantitatively described by the superpositioning effect of Al-3(Sc,Zr) nano-precipitates and Al3Ni microfibers.

Summary: The temperature and concentration dependence of the viscosity of Al-Ni system melts were experimentally obtained, covering a wide range of temperatures (from liquidus to 1700°C) and concentrations (0 to 100 at % of nickel content). The viscosity was found to exhibit a nonmonotonic behavior with maximum values at 50-65 at % of nickel content and a minimum at 85 at %. This nonmonotonic viscosity can be explained by a change in the short-range ordering type in the melt upon varying the concentration.

Summary: The effects of micro-alloyed Mn, Sc, and Zr on the mechanical properties of Al-Ni alloys were studied. It was found that Mn alloying significantly improved the hardness of the alloy, while the addition of Sc and Zr increased the hardness and coarsening resistance. The alloy with added Sc and Zr showed the greatest potential for use as a load bearing structure at elevated temperatures.

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.
