| Abstract Scope |
The FCC Complex Concentrated Alloys (CCA) compositional space is very broad, making it almost impossible to discover promising alloy compositions using conventional approaches. In the present work, the compositional space of CoCrFeNiVAl CCA system has been explored following a combined computational materials science and multiobjective batch-Bayesian optimization strategy searching for alloys with the most optimum mechanical properties under extreme conditions. For each batch, 16 alloys were selected for synthesis at bulk scale, processing, and characterization, which included chemical, microstructural, and mechanical property characterization. For the synthesis, processing, and characterization, special efforts were put into the parallelization and automatization of each step to increase experimental throughput and efficiency. Within a timeframe of less than 9 months, a total of 5 iterations (80 alloys) were conducted which permitted establishing a clear picture of the chemical and microstructural dependencies of the target mechanical properties of strength and strain hardening coefficient. |
