metals and a few alloys. In this paper, the formation of nanocomposites based on complex
high entropy alloys (HEAs) was explored, focusing on the effect of the average carbon
affinity on the phase formation. Two HEA systems were compared: CoCrFeMnNi and Cr 26
Fe 27 Ni 27 Ta 20. For each alloy, around 20–50 at% carbon was added through
combinatorial co-sputtering. Thermodynamic calculations predicted decomposition of these …
