Abstract Scope |
Quinary high-entropy alloys (HEAs) of 2478 different compositions chosen from seven elements (Al, Cr, Mn, Fe, Co, Ni and Cu) were studied using high-throughput combinatorial thin film libraries. Large amounts of composition vs. crystal structure (phase) data were collected from the experimental survey. Thermodynamic calculations using Thermo-Calc and the associated HEA thermodynamic database were performed for these alloy compositions to predict the phases. The computed results were compared with experimental measurements. Both results show that HEAs prefer the bcc structure over the fcc structure with increasing atomic size difference. Detailed and comprehensive comparisons of experimental and computed results will be presented together with interesting conclusions. |
