- Abstract
- The temperature dependence of the damping and the dynamic elastic modulus of Fe-18%Mn-0.6%C twinning-induced plasticity steel with different Al contents were investigated by the impulse excitation internal friction technique. The modulus effect was reduced and the Neel temperature was lowered by the Al addition. The activation energy of the Finkelshtein-Rosin peak increased with Al addition. The Finkelshtein-Rosin peak became broader due to diffusional jumps of the interstitial C with different activation energies resulting from the interaction with substitutional Mn atoms.
