High entropy alloys9/28/2023 These alloys are currently the focus of significant attention in materials science and engineering because they have potentially desirable properties. The term “high-entropy alloys” was coined because the entropy increase of mixing is substantially higher when there is a larger number of elements in the mix, and their proportions are more nearly equal. Hence, high entropy alloys are a novel class of materials. For example, additional elements can be added to iron to improve its properties, thereby creating an iron based alloy, but typically in fairly low proportions, such as the proportions of carbon, manganese, and the like in various steels. Prior to the synthesis of these substances, typical metal alloys comprised one or two major components with smaller amounts of other elements. Hybrid.High-entropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more elements. Lends insight into the complexities of multiple atomic interactions (electronic, chemical, mechanical, magnetic) in multi-component materials Opens up the full field of multi-component and high-entropy alloys to materials and component designers and engineers. Rapid publication of short communicationsīrings together researchers working on metals, ceramics and semiconductors.īrings together researchers working on structural and functional materials. Single focus on high-entropy and medium-entropy materials. The journal publishes original, full-length, peer-reviewed papers review papers (by invitation) and short technical communications The journal is a forum for scientists and engineers who are interested in high-entropy materials, medium-entropy materials and related composites. Papers on sustainability, recyclability and the use of net-shape processing are of particular interest. Practical uses of high entropy materials of interest include: high temperature applications such as for power plants, gas turbine blades, and concentrated solar power permanent magnets and soft magnets for motors and transformers thermoelectric materials, biomaterials for prostheses, corrosion-resistant materials, cryogenic materials, and optically-absorbent materials. Papers on practical applications of high-entropy materials are particularly encouraged, as are papers on structure/property relationships and accelerated design. Papers on the thermodynamics, transformation kinetics and diffusion behavior of high-entropy materials are welcome. Papers combining properties with analytical or computational modeling (first principles density functional theory, molecular dynamics, CALPHAD, Monte Carlo simulations, phase field modeling) and advanced microstructural characterization are published. The journal covers all properties of high-entropy materials including physical (thermal expansion, heat capacity, conductivity), mechanical (quasi-static, creep, fatigue), functional (magnetic, semiconducting, optical, catalytic, antibacterial) and both corrosion and oxidation behavior.
