Abstract：A novel approach was introduced, namely computer-aided cooling thermal analysis, for quantitatively assessing the macroscopic features of alloy microstructures. By analyzing the changes in specific characteristic temperatures and parameters derived from the solidification curve, some valuable insights into the influence of alloy composition and melting processes on the microstructure could be obtained, for example, evaluating the modification effect on the eutectic Si phase, assessing the refinement effect of the initial α-Al phase, and determining the type and precipitation stage of intermediate phases. Unlike conventional methods, the proposed computer-aided cooling thermal analysis could provide a macro perspective on alloy microstructure characterization, eliminating the drawbacks associated with random testing areas and subjective interpretations by personnel. Consequently, this method played an indispensable role in the research and development of high-conductivity (thermal)/high-strength aluminum alloys.
