Sažetak
The application of phase change materials (PCMs) has grown rapidly in the field of thermal management and thermal energy storage. Low melting point metals (LMPMs) and eutectic alloys represent new category of PCMs, which has certain advantages over commercial nonmetallic PCMs like high thermal conductivity and high volumetric latent heat. Two most important criteria for PCMs selection are melting point and the latent heat of melting. In this study, melting and solidification temperatures and latent heat of melting and solidification of the Ga–In and Ga–Sn eutectic alloys were measured using differential scanning calorimetry (DSC). Undercooling tendency of the studied alloys, which is also important criterion for the PCMs selection, was investigated using heating and cooling DSC cycles. Experimentally determined results were compared with the results of thermodynamic calculations according to the CALPHAD (calculation of phase diagram) method and good agreement was observed.
