Heterogeneous nanograined structures have been proposed to achieve unprecedented mechanical properties. In the present work, harmonic structure designed CrMnFeCoNi high entropy alloys were produced by mechanical milling and subsequent spark plasma sintering. A co-relationship between various microstructural characteristics and mechanical properties were established. Due to the peculiar microstructural characteristics, the harmonic structured CrMnFeCoNi high entropy alloys demonstrated a winning combination of high strength, large uniform elongation, and large total elongation to failure, simultaneously. It was also found that the harmonic structure with shell volume fraction of approximately 50%-60% was recommended to be the optimized microstructural characteristics for CrMnFeCoNi high entropy alloy.
