The more alloys we can make from metal scrap, the better. The present paper examines the
prospect of making high entropy alloys (HEA) completely from existing commercial alloys.
Three HEAs were fabricated from pure elemental billets and from scrap ingots with two
different levels of impurities (2 wt% and 9 wt%): a Al 0.3 CoCrFeNi alloy with a single-phase
FCC structure, a Al 0.6 CoCrFeNi alloy with a multi-phase FCC/BCC structure and a Al 0.9
CoCrFeNi alloy with a spinodal BCC/B2 structure. The effect of various impurity levels on the …
