Résumé
L'anisotropie structurale d'un alliage amorphe due au fluage a été observée pour la première fois par diffraction X (méthode de la dispersion en énergie). Cette anisotropie vient uniquement de la polarisation inélastique et disparaît par recuit sous tension nulle. L'écoulement plastique ne fait apparaître aucune anisotropie de structure.
Abstract
We present the first evidence of the structural anisotropy of an amorphous alloy due to creep deformation, detected by energy dispersive x-ray diffraction. The anisotropy is due solely to the anelastic polarization and disappears after zero-stress annealing. The plastic flow leaves no structural anisotropy behind.
