From: Sol-gel Autocombustion Synthesis of Nanocrystalline High-entropy Alloys

(a–c) TG–DSC–MA results obtained for the dried gel prepared from the sol with a fuel–oxidant ratio of 1:1; (d) XRD patterns revealing the crystal structures of the combustion products of the dried gels for different fuel-oxidant ratios; (e) comparison of XRD patterns of CoCrCuNiAl HEAs synthesized by sol–gel autocombustion and MA; (f) XRD patterns of the combustion product of the gels with a fuel–oxidant ratio of 0.8:1 and the schematic illustration of HEOs.
