| Abstract Scope |
The CALPHAD method has been developed for several decades with wide applications in materials design and discovery. It has demonstrated advantages in predicting phase stability of multicomponent alloys, and can further integrate with other phase transformation models. The emerging markets of advanced alloy manufacturing require further development of the CALPHAD-based materials design/discovering approaches. One of the cases is the complex concentrated alloys, which has significantly extended the composition space from single-component rich corner to a much broader composition range with much more unknowns. Therefore, the CALPHAD modeling itself still requires considerable improvements in terms of model and database development, which will also help the accelerated insertion of materials. In this work, the state-of-the-art CALPHAD modeling for alloy design is reviewed such as prediction of metastable phases and stacking fault energy. New opportunities in the complex concentrated alloy development indicate a critical need to improve the low-temperature thermodynamic models and databases. |
