This study develops and validates the accurate mathematical models for thermal conductivity of ternary Al–Cu–Li alloy systems across a broad temperature range (25–700 ℃). The Thermo-Calc software was employed to compute phase formation, phase constituents, and solidification paths along with different temperatures. Then, the Scheil–Gulliver model was applied to calculate the dynamic variation of solid/liquid phase fractions during solidification. Then, thermal conductivity as a new model of temperatures, compositions, and secondary phases for different Al–Cu–Li alloys were derived, based on the Kopp’s law and the differential effective medium (DEM) theory. For experimental validation, the materials density, thermal diffusivity, and specific heat capacity of six representative alloys with various chemical compositions were experimentally determined using thermal dilatometer, differential scanning calorimetry, and laser flash analysis. Comparative analysis between theoretical calculation and experimental data indicates a relatively small deviation of only 7%. Meanwhile, the dynamic variation of thermal conductivity were reliably predicted throughout solidification.

SAXS analysis revealed that the higher organic content shortened the medium-range correlation lengths, indicating alterations in the organization of the silicate network. Nitrogen adsorption dramatically decreased the specific surface area with increased organic substitution (513 <span>(hbox {m}^2)</span>/g for S4 to 1.1 <span>(hbox {m}^2)</span>/g for S2) due to the larger particles that form denser aggregates.
