Abstract Scope |
Eutectic compositions in metallic systems can be instrumental in various applications, such as metallic glasses or eutectic alloys. Although it is relatively easy to determine eutectic temperatures in binary or ternary systems, it requires lots of work when more components are present. In this work, a high throughput numerical method based on the CALPHAD(Computer Coupling of Phase Diagrams and Thermochemistry) approach and the TC-Python Kitware established to determine eutectic compositions of the Al-Mg-Cu-Zn quaternary system as a case study. Firstly, the liquidus and solidus temperatures of each auto-generated composition are determined from TC-Python. Secondly, the eutectic compositions were further ruled out based on the two facts that the liquidus temperature of the candidate composition should be the local minimum among the adjacent compositions, and the temperature difference between the liquidus and the liquidus solidus temperatures should be close to zero. Finally, the candidate compositions were comprehensively compared with existing literature. |
