MicroDICE Final conference – 30 March to 1st April, 2015 – Montpellier, France

Microstructural evolution during HT deformation : advances in the characterization techniques and consequences to physical properties

30 March – 1 April : Conference. 2-3 April : 2-day MTEX open source & free texture analysis training workshop

This meeting, organized in the framework of the ESF project MicroDIce, aims to present a multi-scale view of our present understanding of the processes controlling plasticity and recrystallization at high temperature in geomaterials (ice and rocks). Recent advances in electron microscopy (e.g. HR-SEM-EBSD) allow characterization of the microstructure in complex multi-phase materials from the nanometre to the centimetre scale. Associated with in-situ experiments digital image correlation (DIC), these techniques provide a multi-scale tracking of the deformation field and the associated microstructural evolution. Diffraction pattern cross-correlation techniques in high-resolution EBSD analysis allow accessing the statistical distribution of defects (e.g. dislocations, disclinations), their crystallography and measurement of local lattice rotations of 1/100°. These high-resolution quantitative microstructural methods provide an increasingly sound physical basis for the analysis of heterogeneous polycrystalline behaviour. Our knowledge of processes like recrystallization, where localization of the deformation within grains or along grain boundaries are key factors, greatly benefit from these new developments. On the other hand, a sound understanding of the evolution of microstructures and textures during deformation is also essential for the characterization of the strain-dependence of the rheological behaviour of ice, rocks, and other crystalline materials. Physical properties, like seismic anisotropy caused by strain-induced crystal preferred orientations, can be used to bridge scales from the laboratory or hand-specimen to the planetary applications, as the study of flow or fracturing in glaciers or convection in the deep Earth. In glaciers, for instance, changes in seismic anisotropy due to the evolution of texture with changing deformation conditions may be used for remote monitoring, via seismology, of the deformation.
