High entropy alloy design concept enabled emerging novel materials with enhanced mechanical properties

The bronze age and the subsequent evolution of metallurgy emerged from the accidental discovery of alloys. Since then, the alloy design has been primarily focused on one primary element with the addition of minor elements to get the desired properties for more than 5000 years. This centuries-old alloy design concept has seen a paradigm shift with the birth of high entropy alloys – based on multi-principal elements. Since the first publication in 2004, the design concept based on high entropy alloys has evolved significantly from the initial spotlight on equi-atomic proportion and single-phase microstructure to non-equiatomic proportion and multi-phase microstructure with enhanced mechanical properties. The evolution of this novel design concept provides ample composition window to explore new alloys with enhanced mechanical properties.

The goal of this Research Topic is to explore unique strategies in the development of novel materials with superior mechanical properties based on the high entropy alloy design concept.
Potential topics may include but are not limited to the following:
• Innovative material design strategy and fabrication routes
• Additive manufacturing
• Severe plastic deformation
• Plastic deformation mechanisms
• Mechanical properties at extreme environments
• Creep, Fatigue, and Superplasticity
• Fe-medium etropy alloy – TRIP/TWIP effects and Maraging concept
• Strengthening mechanisms
• Heterogeneous microstructure
