A series of high entropy alloys (HEAs), Cr1-xCuxMnFeNi, was produced by a vacuum arc-melting method. The multi-element systems can crystallize as a single phase, despite containing multiple elements with different crystal structures which often exhibit unusual properties. Their phases, microstructures and base mechanical properties at room temperature were investigated. It has been found that a two face-centered cubic (FCC) crystal structure forms in these alloys with higher Cu addition and a single solid-solution phase with a body-centered cubic (BCC) and two face-centered cubic (FCC) crystal structure forms in these alloys with higher Cr addition. The different hardness between those alloys was observed.Keywords: High-entropy alloy, crystallize, vacuum arc-melting method, solid-solution phase, hardness
