WebThis work investigates the thermal expansion behaviors of Fe30Co30Ni30Cr10-xMnx High Entropy Alloys (HEAs) (x = 0, 5, 10 at.%) from 400 K to 1200 K. Interestingly, comparing to that of Cantor alloy, a decrease in Cr and Mn in Co–Cr–Fe–Mn–Ni system could significantly decrease the thermal expansion coefficient by 45.2%; Fe30Co30Ni30Cr10-xMnx (x = 0, … Web12 feb. 2024 · Infrared spectra of phosphotungstic, silicotungstic, and phosphomolybdic acids and their aluminium-exchanged salts (adapted from refs. [ 34, 35 ]). The main absorption bands assigned to the vibrations of chemical bonds of Keggin anion seen in the infrared spectra of pristine HPAs were also observed in the spectra of aluminium salts.
