Special Issue Information
Dear Colleagues,
During the past two decades, high entropy alloys (HEAs), consisting of multi-principal elements rather than one or two principal elements that exist in traditional alloys, have attracted increasing research interest due to their unique combinations of excellent properties. Through the introduction of refractory elements, refractory high entropy alloys (RHEAs) have been developed since 2010, demonstrating excellent mechanical and functional properties superior to conventional alloys, especially at elevated temperatures. Numerous studies have shown that RHEAs, with high melting points as well as high strength and good corrosion, oxidation and irradiation resistance, have great potential for use in high-temperature applications, such as turbine engines and nuclear reactors.
Although efforts have been devoted to the development of new systems of RHEAs, the investigation of their microstructure and mechanical properties and the exploration of their possible structural and functional applications, these efforts are still far from those necessary for the development of next-generation high-temperature materials. For example, the mechanisms of phase formation, plastic deformation, strengthening and high-temperature oxidation are still under debate. Similarly, the development of tungsten-containing RHEAs, which are extremely suitable for harsh environments such as in nuclear fusion reactors, is still in progress. This Special Issue aims to include the recent progress in the development, deformation mechanisms, functional properties as well as the applications of RHEAs, especially tungsten-containing RHEAs. All original research work and review articles related to the following aspects are welcome and appreciated:
- Design and development of new RHEAs;
- Mechanical properties and deformation mechanisms of RHEAs;
- Functional properties of RHEAs, such as oxidation, corrosion and irradiation resistance;
- Fabrication and processing of RHEAs;
- Development, characterization, processing and application of tungsten alloys;
- Advances in other refractory alloys and HEAs.
