摘要：

The Ru-Ti system was critically assessed by means of the CALPHAD technique. Based on the experimental data, the solution phases (liquid, body-centered cubic, hexagonal close-packed) were modeled with the Redlich-Kister equation and Kaptay equation. A two-sublattice model (Ru, Ti)(0.5)(Ru, Ti)(0.5) is applied to describe the compound RuTi in order to deal with the order-disorder transition between body-centered cubic solution (A2) and RuTi with CsCl-type structure (132). Two sets of self-consistent thermodynamic parameters of the Ru-Ti system were obtained. (c) 2008 Elsevier B.V. All rights reserved.
