Abstract
The influence of preliminary shock-wave loading on the deformation structure formation in the process of following high-rate plastic strain has been investigated. The previous hardening is shown to provide a structural uniformity of the deformation to large value of strain due to the formation of a highly dispersed intergrain structure.
Résumé
L'influence de chargement préliminaire par ondes de choc sur la formation de la structure déformée lors de la déformation plastique ultérieure à grande vitesse de déformation est étudiée. On démontre que le chargement préliminaire détermine l'uniformité structurale de la déformation jusqu'à des valeurs très élevées grâce à la création d'une structure intergranulaire fortement dispersive.
