The traditional inspection of civil infrastructure mostly relies on visual inspection using human inspectors. The non-destructive evaluation (NDE) of civil infrastructure has been an active area of research in recent decades. We illustrate the advantages, disadvantages, and application range of these techniques, and compare them with each other to provide some guidance for HEA study. The first-principles calculations are based on quantum mechanics and several open source databases, and it can also provide the finer atomic information for the thermodynamic analysis of CALPHAD and machine learning.
The empirical model and the machine learning are both based on summary and analysis, while the latter is more believable for the use of multiple algorithms. Here we present and discuss four different calculation methods that are usually applied to accelerate the development of novel HEA compositions, that is, empirical models, first-principles calculations, calculation of phase diagrams (CALPHAD), and machine learning. In order to explore the huge compositional and microstructural spaces more effectively, high-throughput calculation techniques are put forward, overcoming the time-consuming and laboriousness of traditional experiments. High-entropy alloys (HEAs) open up new doors for their novel design principles and excellent properties.
