Computational and experimental studies have increasingly provided details of the grain boundary (GB) wetting and phase transition in various alloys. In this work we present a detailed study of these transitions in polycrystalline Al-Sn eutectic system as a function of temperature, alloy composition and crystallography of GB. The transition temperature of these GB segregated phase was estimated using differential scanning calorimetry while the structural, compositional and morphological characteristics of the Sn rich GBs segregated phase as a function of alloy-composition and GB characteristics were studied using a combination of SEM, EBSD, EDS and XRD based techniques. Results obtained from these experiments will be combined to gain insight to wetting and phase transitions at the GBs.
