| Abstract Scope |
High entropy alloys (HEAs) have proved to be very competitive in many areas and have attracted a great deal of interest in recent times. Despite this keen interest, the majority of HEAs have been developed using ingot metallurgy. However, powder metallurgy (PM) has emerged as a compelling alternative for advancing this alloy category, potentially broadening the scope of nanostructures within HEAs and enhancing their capabilities. The powder route also opens up new possibilities using many different manufacturing routes. This work demonstrates the enormous potential of high entropy alloys obtained by the PM route in the field of extreme properties, competing with the reference alloys in each of these areas: mechanical behavior at high temperatures competing with nickel-based superalloys, and corrosion resistance in contact with salts for cooling in solar concentration plants, and resistance to hydrogen embrittlement competing with stainless steels. |
