TEM study of the aging of palladium-based alloys during tritium storage

Abstract The defects ( 3 He bubbles, dislocations, dislocation loops, clusters of self-interstitial atoms) formed during aging of palladium tritides are analyzed using a combination of transmission electron microscopy techniques. Their evolution under aging together with the effect of the metallic substitution by Rh or Pt is investigated. A comparison with the results previously obtained from X-ray and neutron scattering experiments is also performed.
