Experimental study and thermodynamic calculation of Au-Bi-Sb system phase equilibria

摘要

Phase equilibria in the Au-Bi-Sb ternary system have been studied experimentally and calculated by the CALPHAD method. Three calculated isopleths with molar ratios Au:Bi = 1, Bi:Sb = I and Au:Sb = I were compared with the DTA results from this work. The liquidus projection has been calculated. Two ternary invariant reactions were noted. Calculated phase diagram of isothermal section at 573 K was compared with the results of SEM/EDX analysis. (C) 2007 Elsevier Ltd. All rights reserved.
