Abstract

In this work, we systematically investigated the relationship between microstructure and mechanical properties of CoCrFeNiZrx (x= 0, 0.3, 0.5, 1) high entropy thin films. A transition from single phase crystal to amorphous structure was observed with increasing Zr concentration from 0 at.% to 25 at.%. In the intermediate Zr concentration-range spanning from 7.0 at.% to 12 at.%, Zr addition renders a peak hardness of 6.8 GPa with a crystal-amorphous dual phase structure. In the meantime, we provide reasonable insights into understanding behaviors above. These findings will convey the valuable information for designing ultrastrong high entropy alloys for practical applications.
