Thermodynamic analysis of high entropy alloys and their mechanical behavior in high and low-temperature conditions with a microstructural approach - A review

The present study is an analysis of different investigations of high entropy alloys in different fields of application and themes, but which converge in the line of mechanical behavior at cryogenic temperatures and high temperatures with the main focus on the microstructure and its constitution potential through thermodynamics. The revised chapters are precisely the thermodynamic and metallurgical foundations that govern the design of high entropy alloys, introduce in their different applications in the fields of energy, aerospace, metal shaping, and advanced manufacturing, predictive thermodynamics, microstructural analysis and their importance in the mechanical behavior and formation of strengthening mechanisms, to end with the analysis of the whole document in the application of the mechanical response of high entropy alloys in condition of high temperatures and cryogenic temperatures in addition to dynamic loads such as fatigue and reflecting the importance of the manufacturing process and the microstructure has in the performance at working conditions, leaving in evidence the dependence of the microstructure and its defects as well as its present phases allow to obtain a good behavior at macroscopic level. For this reason, the analysis of the evaluation of mechanical behavior was also linked through multiscale analysis through different applied methodologies and how they are combined in a way coupled to the time and space access system.
