The phase diagram of the section AuSb-InSb in the Au-In-Sb system is established using differential scanning calorimetry. The results identify eight ternary invariants in the quadrilateral AuIn-InSb-SbAu: three eutectic-type reactions at (413.17, 386.6 and 355.4) degrees C; four quasi-peritectic reactions at (390.7, 376.1, 370.3 and 358.4) degrees C and one ternary peritectic at 396.2 degrees C. By taking into account the data of the literature, a representation of the ternary equilibria is given. (C) 2013 Elsevier Ltd. All rights reserved.
