Microstructure and mechanical properties of CoCrFeNiZrx eutectic high-entropy alloys

The emergence of eutectic high-entropy alloys containing Laves phase provides a new and exciting research direction towards developing advanced structural alloys, in light of the inherent advantages of Laves phase at elevated temperatures. In this work, CoCrFeNiZrx alloys were prepared with varying zirconium contents by vacuum arc-melting method. Typical eutectic microstructure was identified in the as-cast alloy having x = 0.5. The alloys...
