However, there are numerous types of high-entropy electrode materials and various preparation methods. Different synthesis methods have distinct effects on material properties. Not all methods can synthesize a variety of elements into a single solid solution phase, and complex preparation methods often l...
For the past decade and a half, however, a new alloying strategy that involves the combination of multiple principal elements in high concentrations to create new materials called high-entropy alloys has been in vogue. The multi-dimensional compositional space that can be tackled with this ...
High-entropy oxides (HEOs) are widely researched as potential materials for thermal barrier coatings (TBCs). However, the relatively low thermal expansion coefficient (TEC) of those materials severely restricts their practical application. In order to improve the poor thermal expansion property and fur...
In addition to the microstructure evolution, high Al content can also affect the non-metallic inclusion (NMI) formation in the high entropy alloys. This is due to Al is a very active element, which can easily form oxide and/or nitride inclusions and lead to the degradation of the mechanical...
[120]. The high-entropy alloy bonding layers formed by EHLA have block structures and good metallurgical bonding with the substrate. In the initial stage of oxidation, aluminum can easily diffuse to form an alumina protective layer, which leads to the pre-oxidation time of this new coating ...

The linear wear ranges from 1.06 · 10–7 for chromium to 12.76 · 10–7 for aluminum. In addition, the linear wear of multicomponent alloys is lower than that of their constituent metals and ranges from 0.35 · 10–7 to 4.38 · 10–7. The linear wear of high-entropy alloys is a ...
Combining the alloying and grain-size effects, NC and nanostructured HEMs have attracted much attention over the past five years. This article outlines the progress in this field and assesses the current state of validation of entropy-based stabilization theories. Synthesis processes, types of material...
