Title

Texture development during dynamic recrystallization in ice

Abstract

Dynamic recrystallization (DRX) which can occur during viscoplastic deformation of metals and minerals induces strong changes in microstructure and texture, and thus in mechanical properties. Current knowledges on the fundamental mechanisms associated with dynamic recrystallization are still limited, in particular for nucleation mechanisms.The present project is focused on DRX on ice. First because DRX is strongly impacting the textures and microstructures of ice in natural environments such as glaciers and ice sheet. Secondly because ice, being a highly anisotropic material, is currently seen as a model material. Indeed, its high viscoplastic anisotropy induces strong strain heterogeneities which are in favour of DRX mechanisms. To our knowledge, there exist no high resolution data of texture evolution during the early stage of DRX in ice, mostly due to the difficulty to obtain data on the very small first nucleus. Samples will be deformed at different levels prior to and during DRX and further analysed in the D19 diffractometer. The CAPS detector provides a 2theta resolution adequate for this analysis aiming at quantitatively determine the orientations of ice nucleus.
