Abstract

Nokeun Park’s affiliation has been updated as shown in this erratum. The third sentence in the following text has been added to the Experimental Procedures section on page 1482 as clarification regarding the chemical composition of the whole sample: The material used in the current study was an equimolar CoCrCuFeNi alloy (20 mol pct for each element) that was cast with the pseudo float melting process that brings almost homogeneous distribution of each element. An as-cast HEA rod 10 mm in diameter and 60 mm in length was homogenized at 1373 K (1100 C) for 12 hours, followed by water cooling. The chemical composition of homogenized specimen was measured by wavelength-dispersive X-ray spectroscopy, and the atomic percent was Co21Cr22Cu22Fe21Ni14.
