Multi-principal element alloys (MPEAs) (a.k.a. high entropy alloys) have attracted intense research interest due to their potential for enhanced properties versus conventional alloys. To date, the vast majority of the MPEA compositions studied have been prepared by casting of a molten mixture of the elemental metals. The present work describes a novel solid state technique whereby a bulk equimolar FeCoCuNi MPEA was processed by the reduction of metal oxides. The influence of heat-treatment parameters on the resulting microstructure of the ceramic derived alloy will be presented. Compared to similar alloys fabricated by melt processing, interesting differences emerged with regard to the composition and distribution of the phases. These will be examined in the light of the different fabrication methods. The potential advantages of the ceramic derived process will be discussed, together with the extension of this technique to other MPEA compositions.
