Special Issue Information
Multiple-element alloys, or high-entropy alloys (HEAs), which normally consist of at least four elements (the concentration of each element is within 5-35 at.%), have recently become a hot research topic in the field of new metallic materials. HEAs are considered a breakthrough with which to design and explore new alloys with excellent properties. However, most HEAs have failed to show good mechanical properties in a single FCC- or BCC-phase structure. Although some studies have tried to design multi-phase HEAs to improve their mechanical properties, most of them failed to show excellent behavior in castability and liquidity, especially considering the large amount of HEAs used in industrial applications, because segregation occurs in the ingot casting process. To overcome this bottleneck problem, the concept of eutectic alloys was introduced to design new HEAs, or the concept of HEAs was introduced to design new eutectic alloys, because it is well-known that eutectic alloys have good castability and liquidity. The HEAs with a eutectic composition and microstructure are multiple eutectic alloys, or eutectic high-entropy alloys (EHEAs). EHEAs are expected to have innovative properties with which to prepare superalloys. For example, the EHEA AlCoCrFeNi2.1, with a mixture of hard BCC and soft FCC phases, can have both high fracture strength and excellent plasticity, and CoFeNi2V0.5Nb0.75, with alternating FCC solid solution and Fe2Nb-type Laves phases, shows excellent fracture strength, yield strength, and plastic strain simultaneously, as well as the possibility of high-temperature applications.
In this Special Issue, we would like to call for papers on new progress in multiple eutectic alloy materials. All research, communication, and review articles are welcome. It is my great pleasure to invite you to submit papers on topics related to the theory, materials’ properties and manufacture, design, thermodynamic calculation, new applications, microstructure and structures, and metallurgy of multiple eutectic alloys or EHEAs.
