Abstract

The isothermal section at 900 °C of the Ti-poor part of the Ni−Ti−Ru ternary system was measured experimentally, combined with SEM-EDS, XRD, TEM and DSC techniques. Four three-phase equilibria regions were confirmed at 900 °C isothermal section and a ternary compound τ with Face-centered-cubic structure can existed stably. The isothermal section at 900 °C measured in this study and the experimental data from our previous work were adopted in the present optimization. The calculated Ni−Ti−Ru ternary system was summarily presented in the form of isothermal sections, liquids projection and reaction scheme, with appropriate comparisons with available experimental data.

镍钛钌三元体系贫钛部分的实验研究和热力学评估

结合 SEM-EDS、XRD、TEM 和 DSC 技术，通过实验测量了镍钛钌三元体系贫钛部分在 900 °C 时的等温截面。在 900 °C等温截面上确认了四个三相平衡区域，并且具有面心立方结构的三元化合物 τ 可以稳定存在。本研究中测得的 900 °C 等温截面和我们之前工作中的实验数据被采用于本次优化。计算得出的镍钛钌三元体系以等温截面、液体投影和反应方案的形式进行了总结，并与现有的实验数据进行了适当的比较。

期刊介绍： The design of industrial processes requires reliable thermodynamic data. CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) aims to promote computational thermodynamics through development of models to represent thermodynamic properties for various phases which permit prediction of properties of multicomponent systems from those of binary and ternary subsystems, critical assessment of data and their incorporation into self-consistent databases, development of software to optimize and derive thermodynamic parameters and the development and use of databanks for calculations to improve understanding of various industrial and technological processes. This work is disseminated through the CALPHAD journal and its annual conference.
