Anelastic relaxation due to interstitial solute atoms in face-centred cubic metals

The behaviour of light interstitial elements dissolved in transition metals of the face-centred cubic structure has been studied by measurements of me chanical relaxation. Those interstitial solute atoms such as C and H Sive r ise to anelastic relaxation effects as they form complexes. such as close p airs. Detailed characterization of such complexes is possible by examining the effects of crystal orientation, solute concentration and temperature on the relaxation effect. Recent experimental results on Ni-CI Ni-C-H and Pd- C systems are presented. (C) 2000 Elsevier Science S.A. All rights reserved .
