AB  - Mechanical   and   electrical properties   of   the   ternary   Bi-Ge-Sn   alloys   were investigated in this study. Calculation of isothermal section at 200, 300, and 25 ºC was carried  out  by  using  optimized  thermodynamic  parameters  for  the  constitutive  binary systems.  Microstructures  of  alloys  were  observed  by  using  optical  microscopy  and scanning electron  microscopy (SEM). Phases in  microstructures have  been detected by X-ray  diffraction  (XRD)  analysis  and  compositions  of  the  phase  by  energy  dispersive spectrometry (EDS). EDS results were compared with the predicted isothermal section at 200  and  300  ºC,  and  good  agreement  has  been  reached  between  them.  The  Brinell hardness and electrical conductivity of selected alloys were measured.  Through ANOVA analysis  and  application  of  the  obtained  results,  an  appropriate  mathematical  model  is proposed for every composition of alloys. By using the appropriated mathematical model for  Brinell  hardness  and  electrical  conductivity,  isolines  for  those  properties  were presented.
