Deformation and Recrystallization Mechanisms in Metals

Objective

Combining strength and formability, metals are indispensable for modern life. Their properties firmly depend on processing, typically involving a series of plastic deformation steps that introduce defects deep below the surface. Our current understanding of the evolution of defect structures is phenomenological, and strongly limited by characterization tools being either limited to surfaces or not available at deformation levels relevant for metal processing.

D-REX strives to radically improve our understanding of structure-property relations in plastic deformation and thermal annealing of metals by visualising and quantifying the structural dynamics in 3D with 100nm resolution – within bulk metals. This will be achieved by developing a unique multi-scale full-field X-ray diffraction microscope enabling time-resolved 3D strain and orientation mapping. Using pink beam diffraction imaging, the time resolution of the microscope is expected to be ~100× better than the existing diffraction imaging methods. The unique experimental results will be used to guide and validate crystal plasticity and phase field models.

D-REX opens a new way to address the unresolved questions of how metals get stronger during deformation and how this affects the annealing processes. For the first time, industrially-relevant deformation levels can be quantitatively and systematically mapped in real-life conditions. This will not only lead to a new scientific understanding, but also provide unprecedented access to critical material parameters from the bulk that will refine material models. More broadly, the novel multi-scale methodology and systematic approach of D-REX will be a game-changer for studies of many hierarchically-ordered crystalline materials.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
