Observation of the formation and sharpening of geometrically necessary boundaries

Observation of the formation and sharpening of geometrically necessary boundaries

We present in-situ visualisation of incidental dislocation boundaries (IDBs) and geometrically necessary boundaries (GNBs) in single-crystal aluminium under tensile load along [111]. Below 5.10% strain, plastic deformation manifests through the stochastic formation of IDBs. GNBs emerge abruptly betw...
