Samples characterized by a mainly screw dislocations substructure generated by low temperature (403 K) deformation, reveal two high amplitude peaks located at 570

depends on the signs of the Burgers’ vector and of the strain. For small strains the process necessitates some acti- vation energy; there is a critical strain above

Résumé.- Des essais de compression à vitesse constante ont été exécutés sur des monocristaux d'alumine entre 25°C et 1800°C sous une pression hydrosta- tique de 1500 MPa..

In this paper we want to investigate the translational gauge theory of dislocations with the most general linear isotropic constitutive relations quadratic in the physical

Thus, the initial localization of the plastic deformation in a single slip system in the form of necking propagating along the specimen with proceeding deformation can be more akin

For the empirical potential calculations and one unique dislocation in the computational cell, the core radius r 0 is determined by considering the defect energy contained in

a) The interaction of geometrical kinks on screw dislocations and hydrogen atoms is null or very weak. b) The SKI component can be attributed totally to KPF on non-screw
