| Abstract Scope |
Nanostructured materials is now a mature research area. High entropy alloys is a more recent area of interest in materials science. This talk will review research on nanostructured high entropy alloys with emphasis on those made by mechanical alloying and high pressure torsion. The paper will begin with a discussion of the seminal research of B. S. Murty and co-workers who first produced nanocrystalline high entropy alloys. This will be followed by a discussion of research of mainly 3d transition metal alloys made nanocrystalline by mechanical alloying. Research on the well-studied Cantor alloy, from the literature and the author’s laboratory will be presented. The possibility of high entropy alloys enhancing the thermal stability of nanocrystalline grain size will be discussed. The author’s and co-worker’s research on a low density high entropy alloy with single phase fcc or hcp structure and an extremely high strength (hardness)-to-weight ratio will be described.
