Abstract Scope |
Multi-principal element alloys (MPEAs), also known as complex concentrated alloys (CCAs) and high entropy alloys (HEAs), are alloys composed of multiple elements with equal or near equal atomic composition, which exhibit outstanding mechanical properties. By definition, numerous combinations of elements with a large variety of compositions can form a MPEA. However, alloy design with trial-and-error experiments is costly and time-consuming. CALPHAD method combined with high-throughput calculation (HTC) provides an efficient way to design MPEAs. In this work, Pandat software with reliable database are employed to perform high-throughput CALPHAD-type calculation. Considering density and cost, Al-Cu-Fe-Ni-Ti quinary system with γ/γ' coherent precipitates is selected after a rough screening in PanHEA database. Experiments were carried out for verification, and the results showed a good agreement with the calculations. We demonstrate that HTC CALPHAD-type calculation is a powerful and reliable method for next-generation material’s design. |
