Based on this, the accurate knowledge of their thermal properties such as melting and solidification temperatures, latent heat of melting, supercooling tendency, etc. is of immense importance. In the present research, low-melting alloy from three cross-sections Bi-Sn50In50, Sn-In50Bi50, and In-Bi50Sn50 (wt.%) was investigated using differential thermal analysis (DTA), and by scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS). Temperatures of phase transformations, determined by DTA, and phase compositions of coexisting phases, determined by EDS analysis, were found to support the corresponding calculated phase compositions quite well. The experimentally obtained results were compared with the results of thermodynamic calculation according to the CALPHAD approach, and a close agreement was noticed.enBi-In-Sn alloysdifferential thermal analysis (DTA)microstructureSEM-EDSconferenceObject
