WEB Self-organised architecture of metals induced by plastic deformation

Wednesday (23.09.2020)
10:25 - 10:40 S: Structural Materials 2
Part of:

We consider the inner architecture of metallic materials at meso- and macroscale that emerges during their plastic deformation as a result of unspecific influences. We will show that plastic instabilities of various kinds can give rise to such architectural patterns. The following structures will be considered from this viewpoint: dislocation mesostructures, a neck occurring in uniaxial tension; multiple necks in composites under direct extrusion; shear bands in tension of plates; various structures occurring under simple shear of layered specimens, which are similar to those observed in geological formations, including folds, boudines, vortices, cleavage, etc. The potential of processing by severe plastic deformation for producing architectured materials (archimats) with self-organised structure will be discussed along with the expected properties of such materials.
