Damping behavior of AlxCoCrFeNi high-entropy alloys by a dynamic mechanical analyzer

•The Al content is related with structural relaxation and damping capability.•Dynamic modulus is insensitive to the frequency especially for storage modulus.•Several internal-friction peaks are observed in the Al-free or Al-lean alloys.•The damping behavior is proposed to be strongly relied on the l...
