About this Research Topic
In the history of the development of human, the discovery and use of metal materials have greatly improved social productivity and are of milestone significance. With the continuous development of society, traditional single main element alloys are increasingly unable to meet people's increasing service needs. Multi-principal element alloys (MPEAs) have greatly expanded the scope of metal material composition design due to their unique physical, chemical, mechanical and service properties, and are expected to play an important role in major engineering fields such as national defense, aviation, ocean, nuclear energy, medical care, and new energy. In recent years, MPEAs have published dozens of research papers or reviews in authoritative international academic journals, showing great theoretical research value and industrial application prospects. Therefore, we are committed to publishing the latest developments and potential applicability of mechanical properties and service performance of MPEAs.
MPEAs exhibit outstanding mechanical properties, such as outstanding specific strength, excellent mechanical properties at high temperatures, exceptional ductility and fracture toughness at low temperatures. However, due to their vast chemical composition space, which is close to infinite, and their complex multiscale microstructural organization, the intrinsic deformation mechanisms and strengthening mechanisms of MPEAs under complex service environments have not been fully elucidated. The emergence of MPEAs has posed fundamental challenges to traditional alloy theories, models, and artificial intelligence methods. Therefore, a deeper understanding is still required regarding the underlying mechanisms behind their exceptional mechanical properties and their overall impact on service performance.
Additionally, the introduction of advanced techniques such as machine learning, high-throughput experiments, and simulations can accelerate material screening and discovery, thereby reducing the development cycle and costs. The growth of knowledge in these fields contributes to the development of MPEAs with outstanding service performance. The aim of this study is to explore the latest advances in the potential mechanical mechanisms of MPEA and its impact on performance, in order to bridge the knowledge gap and provide insights and guidance for exploring the excellent performance of MPEAs. The study covers the following topics (but not limited to):
1. Microstructural organization and design
2. Deformation and strengthening mechanisms
3. Environmental effects and service performance
4. Advanced characterization and performance testing techniques
5. Multi-scale computational modeling and simulations
6. Machine learning with high-throughput experiments and Computing
