Abstract
Des bi et tri-cristaux de Cu-9% at Al ont été flués à 1073 K sous une contrainte de traction de 6 MPa. On compare le glissement aux joints en l'absence et en présence d'un noeud triple et on discute l'influence d'un tel noeud sur la rupture intergranulaire.
Abstract
Cu - 9at. % Al tricrystals and bicrystals were crept at 1073K under a tensile stress of 6 MPa. The difference of sliding behavior between grain boundaries with and without a boundary node was compared. Effects of the boundary node on grain-boundary sliding and intergranular fracture were discussed.
