Special Issue Information

Dear Colleagues,

According to the alloy design with multiple principal elements in the equimolar of near-equimolar ratios—high-entropy alloys (HEAs)—435,897 alloys can be synthesized, provided that 5 of the current 37 kinds of elements commonly used in the preparation of HEAs are mixed together. If the number of principals is set to 3 to 6, this number will reach 2,834,496. At present, 400 kinds of HEAs have been developed, many of which are obtained by means of adjustment according to the existing formula. However, less than 100 HEAs have actually been obtained through mixing different elements so far. This means that there is still tremendous room for exploiting HEAs. To date, many compositions have been designed and the corresponding properties have been investigated, such as mechanical properties, conductivity, electrocatalysis, and even those related to biomaterials. However, the compositions and lattice distortions of HEAs are different from each other even with the same structure, which remarkably raises the difficulty of predicting the behaviors of materials, particularly from the perspective of the micro-structure. Profound physics, which is rooted in the correlation between the intrinsic structural characteristics and properties, is still lacking a large number of journal papers that address HEAs. In addition, as the temperature decreases, the impact of the entropy on Gibbs free energy is attenuated, the chemical disorder in the matrix may be changed, or even element segregation or phase precipitation can easily occur, which may influence the stability of properties. Thus, the stability of properties with temperature should be another important issue for HEAs, different from traditional alloys whose properties are generally stable in a somehow large temperature range. In any case, the difference between local chemical environment and the lattice distortion in HEAs provide us with novel phenomena in chemistry and physics, distinct from traditional alloys. The exciting exploitation and application of these potentially novel properties are expected in future.
