Abstract Scope |
Multi-Principal Element Alloys (MPEAs) are an emerging class of materials with unique physical characteristics and functional properties. To date, the most widely used processing methods for MPEAs are arc melting and mechanical alloying. The study explores the feasibility of a novel process for bulk MPEAs, namely mixed metal oxide reduction (M²OR). In this process individual metal oxides are mixed and reduced to metallic alloys under appropriate processing conditions. The process has been utilized to produce several MPEAs including Cantor alloy, as well as MPEA-ceramic composites with unique microstructures. The microstructures are characterized by x-ray diffraction, SEM and analytical electron microscopy tools such as EBSD and EPMA. The results indicate that a complex interplay between thermodynamics and kinetics dictates the formation of the MPEAs in the M²OR process. The thermo-kinetics of the reduction process and its concomitant effect on the microstructure and properties will be discussed. |
